[00:07:00]  90.5
[00:16:38]  Sorry, guys.
[00:16:40]  I'm running a little late.
[00:16:48]  Hello.
[00:16:55]  Am I audible to you guys?
[00:16:56]  Yeah, I'm going to be audible.
[00:16:58]  Okay.
[00:16:59]  Hi, it's Arpita.
[00:17:02]  I see for React Native.
[00:17:05]  Okay.
[00:17:06]  Yeah, I'd like to introduce Kaushik.
[00:17:10]  He has experience in React Native.
[00:17:12]  So, please go ahead and start with the interview.
[00:17:15]  Okay. Hello, Gaushek. How are you?
[00:17:25]  Hi, sir.
[00:17:26]  Hello.
[00:17:28]  So I've seen your assignment.
[00:17:31]  Can you just quickly run it on your local?
[00:17:33]  Yes, sir.
[00:17:36]  Shall I share my screen, sir?
[00:17:46]  Sir, is my screen visible?
[00:17:48]  Yes.
[00:18:20]  Okay, just can you quickly show me your code operations,
[00:18:24]  all the creating event, deleting event,
[00:18:25]  and drag and drop feature that we asked.
[00:18:28]  Okay.
[00:18:30]  Like, firstly, I'll show the create functionality.
[00:18:34]  Yeah.
[00:18:46]  You are running it on your local device?
[00:18:50]  Yes, I am running it on screen.
[00:18:54]  Android Studio?
[00:18:57]  Like in Android Studio, I don't have that Google account.
[00:19:00]  So I'm running in my local device.
[00:19:04]  OK.
[00:19:15]  Just change the time once.
[00:19:23]  Yes, like any day.
[00:19:25]  Okay.
[00:19:29]  Keep it at ease.
[00:19:33]  Okay.
[00:19:56]  Okay, go to the calendar interview.
[00:20:03]  Yeah, drag the 7 to somewhere else.
[00:20:05]  Okay.
[00:20:20]  Yeah, it is.
[00:20:22]  All right, you moved it to which date, sorry?
[00:20:24]  18th.
[00:20:25]  18th, okay.
[00:20:27]  Not just, okay.
[00:20:29]  Just open the event and edit it.
[00:20:32]  Okay, yeah, I'm editing.
[00:20:37]  Like for editing and delete, I have implemented this file to write.
[00:20:41]  Nice.
[00:20:45]  We just change the date.
[00:20:47]  Like, no, sir, I have not kept that changing the date functionality for this.
[00:20:54]  OK, OK. So you can change time and location.
[00:20:58]  Right. Yes.
[00:21:00]  OK, for date, you have to drag and drop it again.
[00:21:47]  So it is changed.
[00:21:50]  Like for deleting.
[00:21:52]  Again, I'll go for delete.
[00:21:53]  Yes.
[00:22:05]  Just quickly click on any date like for example 21st that is Sunday.
[00:22:11]  Okay.
[00:22:17]  And how are you calling this events from Google Calendar?
[00:22:21]  Yes, from the Google Calendar itself.
[00:22:24]  Okay.
[00:22:25]  In the code now, can you show me the code where you added the drag and drop function?
[00:22:31]  Okay, sir.
[00:22:32]  Wait.
[00:22:36]  You can close your device if you want.
[00:22:39]  Okay.
[00:22:45]  But drag and drop functionality, I have used a pan responder and animated view.
[00:22:52]  like this is the code for drag and drop functionality.
[00:23:01]  Firstly, we'll set the dragging event like for long press.
[00:23:06]  I have used long press for starting the drag functionality.
[00:23:11]  Whenever the user long press on any event.
[00:23:16]  Like how you're fetching this drop date?
[00:23:19]  This go drop date.
[00:23:20]  Oh, yeah.
[00:23:22]  Whenever the user releases the cache share, we will take the X and Y from the event and
[00:23:37]  we will check whether this point in which box this point is present.
[00:23:44]  And in that point, date will update that date.
[00:23:50]  Okay.
[00:23:50]  And if it's not present inside the box, let's say you are dragging it and you drag it above the grid, your date grid, what will happen?
[00:24:01]  Like it won't update.
[00:24:03]  So, okay, cool.
[00:24:07]  All right, and can you show me that package?
[00:24:11]  Okay.
[00:24:19]  You go to dev dependencies.
[00:24:27]  All right.
[00:24:29]  Okay.
[00:24:30]  Now, show me the layout for your navigation.
[00:24:34]  Okay.
[00:24:38]  Have you only used a stack navigator in this entire system application?
[00:24:44]  Using stack screen, okay.
[00:24:53]  Okay, here you used one param in screen options that is header shown.
[00:24:59]  Yes, sir.
[00:25:01]  What it is used for and what are the similar options available here?
[00:25:06]  Do you know about that?
[00:25:09]  Like say I'm unable to get your push.
[00:25:11]  You have passed it header shown false.
[00:25:14]  What if I pass it true?
[00:25:16]  Like we'll get the header in the screen.
[00:25:19]  Okay.
[00:25:20]  And what will header display?
[00:25:22]  Like the screen name, the particular screen name.
[00:25:27]  And where it will fetch that screen name from?
[00:25:30]  Like we are mentioning here, like we are giving a name like splash.
[00:25:34]  If we mention header shown true, we'll get a splash as a header.
[00:25:40]  Okay, fine.
[00:25:43]  Okay, just open your Google Chrome once.
[00:25:47]  Okay.
[00:25:49]  and the console there.
[00:25:52]  Okay.
[00:25:53]  Console.
[00:25:54]  Yeah.
[00:25:56]  This open new tab, yeah.
[00:26:04]  So what is your what you're asking about?
[00:26:09]  Okay, okay.
[00:26:10]  Just close this search box.
[00:26:12]  You're using Windows, right?
[00:26:14]  So type control shift J.
[00:26:17]  Open new tab and then type the new tab.
[00:26:22]  Okay.
[00:26:23]  Then not in this one, just open the job, then type that.
[00:26:32]  Yeah, go to console.
[00:26:34]  Okay, now just clear it.
[00:26:43]  Yeah, that, yeah.
[00:26:45]  Now write a function to reverse a string.
[00:26:52]  strings are okay
[00:27:51]  Okay, if it's like you can go to code sandbox, it will be easy for you.
[00:27:55]  Okay.
[00:27:56]  Let's type code sandbox and JavaScript.
[00:28:05]  You open the JavaScript version here.
[00:28:16]  go to your JS file.
[00:28:28]  where this index dot and this go to index for this now here you can type that and call that function
[00:28:35]  in the console or every one
[00:28:52]  I just signed in here, don't read it and sign it yet.
[00:28:56]  Okay.
[00:28:57]  Use your Google account and sign in.
[00:29:12]  Now you'll be able to edit.
[00:31:50]  is long this function.
[00:31:53]  Okay.
[00:32:19]  Open the terminal in the window next to you.
[00:32:24]  Not here, not here on the right side.
[00:32:28]  You will see an option.
[00:32:29]  Just drag this meet screen and you'll see the option of terminal in the bottom bar.
[00:32:36]  Not like that.
[00:32:54]  No, the preview. You have to open the preview.
[00:32:58]  Yeah, just on three dots.
[00:33:02]  Enable, yeah.
[00:33:03]  Just click it on again.
[00:33:05]  Do it again.
[00:33:21]  All right, just copy paste this whole code and open this tab again.
[00:34:24]  No, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no,
[00:34:27]  let it open.
[00:34:28]  It's opening in the right window.
[00:34:41]  Also make sure your connectivity is good.
[00:36:17]  You have to call that in.
[00:36:42]  Okay, just quickly check the chat.
[00:36:46]  I have given you one more link.
[00:36:48]  It will be more easy.
[00:36:54]  The team's chart, you will see it there.
[00:37:17]  I'm going to go ahead and start.
[00:37:39]  Can we do something about this?
[00:37:42]  Yeah, just I'm checking.
[00:37:46]  Okay.
[00:38:03]  That will be the problem.
[00:38:04]  Sorry, again.
[00:38:14]  Thank you.
[00:38:55]  Hello, have you now?
[00:38:57]  Yeah.
[00:38:58]  You can carry on.
[00:39:05]  Okay, I'm just sending you the link again.
[00:39:11]  Open this one.
[00:39:14]  Here in the JS window, you can just quickly type that function.
[00:39:19]  You can close this window.
[00:39:23]  Yeah.
[00:42:35]  See, now you have got a condition of infinite loop.
[00:42:39]  So just quickly debug it, just figure out how can you solve this.
[00:43:20]  Yeah.
[00:43:28]  All right, fine.
[00:43:30]  Okay, quickly open the chat again.
[00:43:37]  And tell me what will be the output of this.
[00:44:15]  You are not audible, Kaushik.
[00:44:24]  Hello.
[00:44:25]  Yeah.
[00:44:26]  Am I audible, sir?
[00:44:27]  Yeah, yeah.
[00:44:28]  Yeah.
[00:44:29]  We'll get six as output, sir.
[00:44:32]  Okay.
[00:44:33]  And how?
[00:44:34]  Like, firstly, the reduce function will take first two numbers as a as one and b as two.
[00:44:43]  and it will add both of them and it will return back to the list as a 3 and again it takes a 3 as a and this 3 as b and it will add and it will return back the 6 to the list.
[00:44:58]  Okay.
[00:45:00]  Also tell me the output of this one.
[00:45:05]  Okay.
[00:45:10]  like it will be five I guess like I'm not sure about it okay and why is that
[00:45:19]  happening let's say your answer is correct
[00:45:28]  like the JavaScript will like they convert this string to the number.
[00:45:39]  So what's that process is called?
[00:45:43]  Like I am unable to remember the name of the process, but I know that process will occur.
[00:45:49]  That is time conversions.
[00:45:51]  Okay.
[00:45:53]  And what will be the output of this one?
[00:45:57]  This will be 61 in yesterday.
[00:46:00]  Okay.
[00:46:02]  And same if I do just the same.
[00:46:17]  Now what will be the output?
[00:46:21]  It will be the same as 61.
[00:46:29]  Okay, can you open that code pen again?
[00:46:33]  And
[00:46:34]  the Fibonacci series
[00:46:36]  up to
[00:46:38]  let's say 10th.
[00:46:40]  N is 10.
[00:46:43]  Okay.
[00:48:19]  They're calling the wrong function.
[00:48:21]  Hello.
[00:48:22]  Okay.
[00:51:42]  Yes, sir.
[00:51:43]  Okay.
[00:51:44]  Can you optimize it?
[00:51:50]  I'll try to optimize it.
[00:51:51]  Okay.
[00:52:06]  Also, instead of printing this array, I want you to print these numbers individually and comma separated.
[00:52:14]  Okay.
[00:52:20]  Just tell me the approach, what approach you will take.
[00:52:23]  Like I'm thinking directly we can make a console over here.
[00:52:30]  No, I don't think that will work.
[00:52:32]  But so see, the better approach will be you have to write a loop inside that function.
[00:52:40]  Okay.
[00:52:41]  So you have done two good things here.
[00:52:44]  Like first this n0, n1.
[00:52:48]  And the secondary is that return is right, but you have to write it inside a loop.
[00:52:54]  And the iteration will increase and it will push into this fifth series array.
[00:53:00]  Then you have to print this array items individually.
[00:53:04]  In that case, you are just running loop once your function is sorted, your code will look clean.
[00:53:10]  Okay.
[00:53:11]  Okay, sir.
[00:53:13]  like you got that right?
[00:53:15]  I said thank you for the approach.
[00:53:17]  Okay, okay.
[00:53:18]  Just look at the chat once again.
[00:53:21]  Okay.
[00:53:22]  See, I have given you two loops here.
[00:53:27]  Okay.
[00:53:29]  Can you tell me what will be the output of both of them?
[00:54:04]  like the output for the functions like will be the same output i guess okay and the output will be
[00:54:14]  something like uh firstly it will print zero and then after one second it will print one
[00:54:20]  and after two seconds it will print two and after three seconds it will print three
[00:54:28]  and so on.
[00:54:29]  Okay, just copy the first loop and run it in the code pen.
[00:54:39]  So you are saying the output will be first I'll get one, two, three, four and so on in the intervals, right?
[00:54:49]  Yeah, I'm thinking.
[00:54:52]  see what's the output here the output is five so it took how many times uh in five seconds right
[00:55:02]  yeah so okay and now just comment it out and copy the second loop
[00:55:24]  Now check the console.
[00:55:32]  Okay, now just look at this both loops and tell me what's the difference here.
[00:55:52]  like initializing the variables like in the first loop we are initializing the variable using var
[00:55:58]  and in second loop
[00:56:00]  We are initializing using let.
[00:56:02]  Okay, so now can you think of any way how it is different?
[00:56:08]  The logic is same.
[00:56:09]  I just change the variable declaration, right?
[00:56:13]  Yes.
[00:56:13]  So what can cause this different nature?
[00:56:19]  Just think about it.
[00:56:27]  like
[00:56:31]  I think there is a functional scope.
[00:56:38]  And let is global scope, I think.
[00:56:41]  But we are using both of the loops in the global scope, right?
[00:56:45]  We are not calling it inside any functions.
[00:56:49]  Yes.
[00:56:50]  So the scope of both of these are same here.
[00:56:56]  Yeah.
[00:57:02]  Just Google it.
[00:57:04]  Okay.
[00:57:06]  You want chat GPT now.
[00:57:08]  You can use chat GPT as well.
[00:57:10]  Okay.
[00:57:14]  If copy paste both the function ask what's wrong here, why are you getting different outputs?
[00:57:21]  Okay.
[00:58:25]  Okay.
[00:58:26]  Got the point?
[00:58:27]  Yes, sir.
[00:58:28]  Now explain it to me.
[00:58:31]  Okay.
[00:58:32]  In the first function, like there is a functional scope variable, like whenever the set timeout
[00:58:41]  is called, like on that time, the i is set to be 5.
[00:58:48]  So, whenever the set timeout is executing, the value is already became to 5 because it
[00:58:56]  is a functional scope variable.
[00:58:59]  Then our way printing will get all files, but in the case of a.
[00:59:05]  there we declare in using let for every every time out like for every exhibiting of timeout
[00:59:16]  the j value will be different because it is a scope
[00:59:23]  and how these different scope affecting this
[00:59:27]  Sir?
[00:59:28]  These different scopes are affecting the output, right?
[00:59:32]  Yes, sir.
[00:59:33]  And why is it so?
[00:59:38]  Because the farm.
[00:59:40]  Okay.
[00:59:41]  Remember I asked you a question last time about hoisting.
[00:59:47]  Sir, can you please repeat?
[00:59:49]  I asked you a question about hoisting last time, remember?
[00:59:52]  Yeah, yes.
[00:59:54]  It's the same concept here, the hoisting here.
[00:59:57]  See, so which of the element is now hoisted now?
[01:00:01]  War or let?
[01:00:05]  The wire is hoisted.
[01:00:07]  Okay.
[01:00:11]  So what happened here?
[01:00:13]  It just went inside the loop.
[01:00:15]  Okay.
[01:00:16]  Okay.
[01:00:17]  And set timeout took a time.
[01:00:20]  In that time, the loop value also incremented.
[01:00:23]  So, VAR's value now incremented to first,
[01:00:26]  then second, then third, then fourth, and then fifth.
[01:00:29]  Okay.
[01:00:30]  That's why you are getting 555 each time.
[01:00:33]  But let is not wasting itself.
[01:00:35]  That's why value is incrementing after the loop.
[01:00:40]  Okay.
[01:00:41]  Okay.
[01:00:42]  After the step, sorry.
[01:00:44]  Thank you, sir.
[01:00:46]  Thank you for sharing this.
[01:00:49]  Okay, just open the code pen again and type two arrays.
[01:00:54]  One is number 567.
[01:00:59]  declare two arrays.
[01:01:06]  5, 6 and 7.
[01:01:07]  Yes.
[01:01:09]  Okay.
[01:01:10]  And the second area is 89910.
[01:01:21]  Now, how would you merge these two arrays?
[01:01:25]  Like I want the output to be 5, 6, 7, 8, 9, 10.
[01:01:28]  Like just we can simply add both arrays.
[01:01:32]  Or we can use spread operator.
[01:01:51]  Don't create another variable.
[01:02:17]  See, no, no, no, stop there.
[01:02:21]  Yeah, see the output is 5,6.
[01:02:24]  Okay.
[01:02:25]  Yeah, the output is 5,6,7,8, then 9,10.
[01:02:32]  But I want 5,6,7,8,9,10.
[01:02:36]  Okay.
[01:02:37]  How do you do that?
[01:02:38]  Like we can use spread operator.
[01:02:49]  Oh, sorry.
[01:02:56]  Yeah.
[01:02:58]  Fine.
[01:02:58]  Okay, but I don't want these arrays, array brackets, sorry.
[01:03:03]  Okay.
[01:03:04]  How do you do that?
[01:03:16]  Where are you getting this five from?
[01:03:17]  Okay, okay, okay.
[01:03:19]  All right.
[01:03:46]  I think we should store this thing in another variable, then we can print.
[01:03:51]  Then we won't get the...
[01:03:52]  We can only create two variables, that is array1 and array2.
[01:03:55]  That's the given.
[01:03:56]  We have to compromise.
[01:03:58]  We don't want to compromise the space here.
[01:04:08]  You can manipulate the same variable.
[01:04:13]  So you can manipulate the same variable, but you can only declare two variables.
[01:05:06]  Again, that's seven and five.
[01:05:10]  Okay, no, the below is out.
[01:05:12]  Okay, okay, okay.
[01:05:16]  Yeah, but I don't want these brackets.
[01:05:18]  I just only want values.
[01:05:37]  All right, I'll give you one hint.
[01:05:40]  There's a method in JavaScript to do the same.
[01:05:45]  Can you remember that?
[01:05:50]  You can use dot map.
[01:05:53]  Dot map, but it will create one array more.
[01:05:57]  You know how map works?
[01:05:59]  Behind the same maps create one additional array,
[01:06:03]  whether you use it or not, but it will consume your RAM.
[01:06:07]  Okay.
[01:06:07]  So the main constraint here is I don't want to compromise my space.
[01:06:13]  Okay.
[01:06:22]  I am unable to remember the methods.
[01:06:41]  Sorry, use these two arrays.
[01:06:45]  One is 1, 2, 3.
[01:06:47]  Okay.
[01:07:05]  And the other one is 236.
[01:07:09]  234.
[01:07:20]  Okay.
[01:07:21]  Okay.
[01:07:22]  Now, can you give me, I want two output here.
[01:07:27]  One is the union of these two arrays and the other is intersection of these two arrays.
[01:07:35]  There will be two print statements.
[01:07:39]  One will be printing the union and the second one will be printing intersection.
[01:07:48]  Okay.
[01:09:43]  Sorry, sir, I'm unable to get the logic.
[01:09:47]  Okay, okay.
[01:09:47]  Can you quickly tell me your thought process about this?
[01:09:52]  How would you, like...
[01:09:55]  Give me a quick algo.
[01:10:02]  I'm thinking to iterate a for loop for these two arrays and we'll check whether this element
[01:10:11]  is the array 2 or not.
[01:10:16]  For intersection, we'll check whether the element is present in array 2 or not and using
[01:10:22]  that we'll create a new array and we'll print that array.
[01:10:30]  Okay, also how would you check if let's say I've given you a number 4 if it is available in array 2 or not?
[01:10:38]  Like we can use dot find method to check whether the number is present or not.
[01:10:45]  Okay, and what if it is like...
[01:10:48]  iterating multiple times let's say you have four in two positions okay but you
[01:10:56]  want to only fetch the first one the first position
[01:11:23]  No, just quickly tell me, you don't have to write it.
[01:11:26]  Just like by using dot find method, we can get the only first number.
[01:11:33]  Okay.
[01:11:34]  And what about if I want to fetch the last occurrence?
[01:11:40]  Oh.
[01:11:47]  like there is a L index like I'm there is a method called L index like left left index
[01:11:59]  I will give you the last value.
[01:12:02]  I'm thinking so.
[01:12:28]  I'm thinking that we can use our index of four.
[01:12:33]  We can get the other another index of that particular number.
[01:12:39]  Okay, that's it from my side.
[01:12:44]  If you have any questions.
[01:12:48]  Yeah, that's it.
[01:12:50]  You can stop presenting as well.
[01:12:52]  Okay.
[01:13:01]  Can I leave the meeting?
[01:13:04]  Sorry?
[01:13:05]  Can I leave the meeting, sir?
[01:13:07]  Yeah, sure.
[01:13:12]  Yeah, I have enough.
[01:13:16]  Okay, so this is from my side.
[01:13:20]  I'll talk to Nishant and he'll get back to you.
[01:13:24]  I'll pass on my feedback.
[01:13:27]  Okay.
[01:13:27]  Yeah, any suggestions?
[01:13:30]  Yeah, like he was good at basics, but he should go a little bit for the intermediates.
[01:13:38]  Like if you can see the chat, like this for loop question that should be like easy, not at intermediate level.
[01:13:48]  The hosting was the answer.
[01:13:50]  I remember he answered the hosting in our previous rounds.
[01:13:55]  But you should be able to solve these kind of questions.
[01:14:01]  Yeah.
[01:14:03]  So, if we train him according to your expectations, would you consider interviewing him again?
[01:14:12]  Sorry, your voice is breaking a little bit.
[01:14:15]  Yes, am I audible now?
[01:14:17]  Yeah.
[01:14:18]  If we train the candidate according to your expectations, would you be interested in interviewing the candidate again?
[01:14:29]  Okay, but do you have anyone else?
[01:14:34]  For that, maybe I have to check with the team.
[01:14:38]  The candidate had also done his project as given by Nishant.
[01:14:45]  Did he get an opportunity to explain it for you?
[01:14:49]  Yeah, he explained it to me but see the project wise he was good. I have seen his code also. I was impressed and also the first round I only took the first round. Actually someone else had to take the second round today but he is on sick leave.
[01:15:07]  That's what I had to take. I have given the positive feedback last thing, but I think he should like study a little more.
[01:15:16]  Otherwise, it will be like.
[01:15:19]  I think like the questions I asked was not on the hard level.
[01:15:23]  I went so easy to medium easy type.
[01:15:28]  I was hoping he will be able to solve this but I'll share the explained feedback and
[01:15:37]  Nishant will be the one who will get the results of this.
[01:15:40]  Thanks, thanks.
[01:15:41]  So I'll also discuss with Akshita and our program manager.
[01:15:46]  Let me see like if we have got any more candidates for trained and react native.
[01:15:51]  And if there are, I'll get back to you.
[01:15:53]  Okay.
[01:15:54]  Thanks.
[01:15:55]  Thanks for your time.
[01:15:56]  Thank you.
[01:15:57]  Thanks.
[01:15:58]  Bye bye.
