[00:04:17]  Good morning.
[00:04:22]  Am I audible?
[00:04:23]  Yes, ma'am, you're audible.
[00:04:25]  Okay, great.
[00:04:27]  So, alright.
[00:04:29]  So, from where are you joining this call, Harshit?
[00:04:33]  Currently, I am in my college hostel.
[00:04:38]  So, Ranchi Jharkhand.
[00:04:44]  Yes, ma'am.
[00:04:47]  Okay.
[00:04:48]  So, can you tell me...
[00:04:53]  Just I'm taking a look at your resume.
[00:04:56]  So you were in turning with Next Crest Media.
[00:04:59]  All right.
[00:05:00]  So, Harshit, your institute is fine with you going for a six-month-long on-site internship?
[00:05:06]  Yes, ma'am.
[00:05:07]  Like, I'm in the eighth semester, so they provide the NOC this semester.
[00:05:11]  Oh, okay.
[00:05:12]  And I believe you know that you'll have to relocate to Hyderabad for this internship, right?
[00:05:18]  Yes, I know that.
[00:05:20]  So you're fine with that too?
[00:05:21]  Yes.
[00:05:23]  Okay, that is great.
[00:05:24]  All right.
[00:05:26]  So Harshit, the reason why I scheduled this call is because I wanted to test you on your, you know, Mernstack skills in order to make sure that we can present you for the, you know,
[00:05:38]  technical interview with the technical managers.
[00:05:41]  I'll be assessing you first.
[00:05:44]  Okay, so we'll begin.
[00:05:46]  I'll just start the recording and I'll start with my introduction as well.
[00:05:53]  Okay.
[00:05:55]  So this is Shikha here.
[00:05:57]  I'm working as a talent acquisition team leader here.
[00:06:01]  I'm leading a team of talent acquisition specialists and me and my team looks after the entire hiring needs for Techolution.
[00:06:08]  So that's a quick intro about me.
[00:06:12]  Hey, one thing I have noticed, Harshit, can you change your name to Harshit Singh?
[00:06:18]  Because right now it's Neeru Singh.
[00:06:20]  It's very confusing.
[00:06:21]  In the upcoming interviews, that could cause a problem, okay?
[00:06:24]  Okay, ma'am, I will change that.
[00:06:30]  will begin then.
[00:06:32]  Can you tell me what are meta tags?
[00:06:37]  Meta tags like in HTML.
[00:06:40]  So like in meta tags like we can tell like what the language will be.
[00:06:47]  And it is also like used for SEO purposes.
[00:06:51]  We can also put a description of our website in the meta tags.
[00:06:58]  All right.
[00:06:59]  Can you tell me, let's go to CSS.
[00:07:02]  Can you tell me what is specificity in CSS?
[00:07:06]  Interesting.
[00:07:08]  What is specificity in CSS?
[00:07:12]  Specificity.
[00:07:13]  Yes.
[00:07:17]  Specificity, I don't know about that, man.
[00:07:22]  Okay.
[00:07:23]  So for styling, you know, what do you use?
[00:07:26]  What are you familiar with?
[00:07:28]  I mostly use Tailwind CSS.
[00:07:31]  So, like I...
[00:07:34]  So, while like writing the divs, I just put a...
[00:07:39]  Class and I can just use tailwind CSS I can just give background color like BG red like that not like making a whole class and then taking care of CSS in some other file
[00:07:55]  Okay, all right.
[00:07:57]  Can you tell me, let's go to JavaScript now.
[00:08:00]  Can you tell me what is debouncing and throttling?
[00:08:03]  Okay, debouncing is like it is used in many sites like in Amazon.
[00:08:08]  So whenever a user is typing something,
[00:08:12]  After the user stops typing, there will be a time frame after which a function call will happen.
[00:08:18]  And it will always happen after user stops typing and a certain time limit has passed and then a function call will happen.
[00:08:25]  And throttling is that a function call will happen every 200 milliseconds or some time.
[00:08:31]  It will like occur periodically every 200 or 300 milliseconds.
[00:08:38]  All right.
[00:08:41]  Can you tell me?
[00:08:44]  Okay, I guess that should be fine.
[00:08:46]  Let's go to React now.
[00:08:50]  Yes.
[00:08:50]  Can you tell me, have you worked on...
[00:08:56]  Custom hooks.
[00:08:58]  I have like implemented one use switch hook.
[00:09:05]  So like it's for like, it's a custom which is used to, which is used when fetching the data from the backend.
[00:09:12]  And it likes uses use effect under the hood.
[00:09:18]  Can you tell me prototype chain and inheritance?
[00:09:24]  And throughput?
[00:09:27]  Prototype chain.
[00:09:30]  It's a prototype chain.
[00:09:31]  Okay, ma'am.
[00:09:32]  Okay, so prototype chain, it's like, because JavaScript is an object-oriented language, so always in it, like, if we like, suppose we initialize a string also.
[00:09:45]  So we can also like check it prototype.
[00:09:47]  First, it will show us, like every variable, whether it is an integer, whether it is a string, is always an object.
[00:09:57]  And like suppose you like
[00:10:00]  make a when you check for the prototype of a string or a class or an so it will always point to an object inheritance is like
[00:10:14]  when a child class inherits the attributes and methods of the parent class
[00:10:23]  Alright.
[00:10:26]  Can you tell me about currying function?
[00:10:30]  Cutting function.
[00:10:32]  Yes.
[00:10:37]  I don't know about that one.
[00:10:44]  All right.
[00:10:46]  Let's go to React again then.
[00:10:48]  So can you tell me what does memory leak in React and how do we fix that?
[00:10:53]  Oh man, what do you think of him?
[00:10:56]  I'm like, uh...
[00:11:01]  Memory leak.
[00:11:02]  I'm like, can you like explain more about what you mean by memory leak?
[00:11:08]  Memory leak is itself is, I guess, you know, a term.
[00:11:12]  So.
[00:11:15]  It's fine if you don't know it.
[00:11:17]  We'll just move on.
[00:11:19]  Can you tell me, have you worked with TypeScript or you're just working on JavaScript?
[00:11:25]  Yeah, I've worked with TypeScript.
[00:11:29]  Can you tell me...
[00:11:32]  The difference between type and interface.
[00:11:37]  the difference between type and interface.
[00:11:45]  Interface like we can suppose like we well we let a class extend an interface so like the class has to always like implement all the functions which are present in the interface
[00:12:01]  and type
[00:12:06]  Type like is used for like
[00:12:12]  Type, like suppose we are getting some data from the backend and we know in which format it will come.
[00:12:19]  So like we can initialize a type for it and give it to that object.
[00:12:25]  Okay, all right.
[00:12:27]  Can you tell me about your experience with middleware?
[00:12:31]  Oh, middleware.
[00:12:33]  So middleware, I like use it as an API gateway.
[00:12:37]  So suppose like the front end is sending requests to the backend, it will send the token.
[00:12:43]  So, in the middleware, I just verify the token and put the user details from the database in the middleware and then the call goes to the main API point.
[00:12:55]  And I also implemented one role-based access in the middleware.
[00:13:05]  That is great.
[00:13:05]  You have worked on R-Back.
[00:13:07]  So can you tell me what is a file system in Node?
[00:13:13]  File system in node.
[00:13:15]  Yes.
[00:13:16]  Okay.
[00:13:23]  Then the FS library.
[00:13:29]  I mean, you can tell me what it is.
[00:13:42]  All right.
[00:13:46]  Okay, so you have worked with MongoDB in the database, right?
[00:13:51]  Can you tell me what is aggregation query in MongoDB?
[00:13:56]  Ok, é a tradução do correio.
[00:14:15]  Okay.
[00:14:16]  That's fine.
[00:14:18]  Yes.
[00:14:19]  You know my bank account, right?
[00:14:23]  No problem.
[00:14:24]  Can you share your screen?
[00:14:25]  We'll do some problem solving then.
[00:14:27]  Okay.
[00:14:45]  So you explained me the debounce function, right?
[00:14:49]  How it works.
[00:14:50]  So can you implement a debounce function that ensures a function is called only after a delay?
[00:14:56]  Suppose the delay is of 300.
[00:15:00]  80 seconds.
[00:15:01]  So if there is a delay of inactivity, then, you know, the function will be called.
[00:15:07]  If you want, I can share this with you.
[00:15:13]  So I'm so like, where should I implement that on?
[00:15:17]  You can open any online editor.
[00:15:22]  Remember, screen is visible?
[00:15:24]  Yes, yes, it's visible.
[00:15:54]  So we can like first.
[00:15:59]  declare a variable, then a function,
[00:17:23]  Is this cooking?
[00:17:28]  Can you run it?
[00:17:56]  All right.
[00:17:58]  Okay, I guess that's good.
[00:18:02]  Let's do another one.
[00:18:07]  Do you know about deep object comparison?
[00:18:15]  Deep object comparison.
[00:18:18]  Yes.
[00:18:26]  I don't know about that deep object comparison.
[00:18:30]  It's like the first time I've heard about it, deep object comparison.
[00:18:34]  And so, like, are we, like, comparing objects here based on their addresses or based on their types?
[00:18:43]  It's a deep or shallow copy thing.
[00:18:47]  Right, yes.
[00:18:49]  Okay, ma'am.
[00:18:50]  Like in shallow copy, suppose like there are two objects, like they are pointing to the same address.
[00:19:00]  But in deep copy, there are two similar objects, but they are pointing to two different addresses.
[00:19:12]  Can you...
[00:19:15]  Write a function deep equal where there are object one and object two and it checks that if two objects are deeply equal or not.
[00:19:25]  I can maybe share a test case with you.
[00:19:31]  You can take a look at the chat box.
[00:19:54]  Yeah, you can check the chat box.
[00:19:56]  Okay.
[00:20:02]  And then it should return true.
[00:20:05]  Yes, it should return true if they are equal.
[00:20:08]  If they are not equal, it should return false.
[00:25:52]  No, I'm not able to do it.
[00:26:02]  All right.
[00:26:03]  Yeah, I guess that's all from my end, Harshit.
[00:26:06]  I am good.
[00:26:08]  So I'll be sharing the details with you most probably by end of the day.
[00:26:15]  I'll let the interviewer review the recording and he'll share the feedback.
[00:26:21]  So I'll let you know most probably by end of the day today, you'll get the update.
[00:26:25]  Okay.
[00:26:27]  Thank you.
[00:26:28]  All right.
[00:26:28]  Thank you.
[00:26:30]  Thank you, Arshad.
[00:26:30]  Have a great day.
