When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.

To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.

What to expect

Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.

//Elegant Way to Find File Extension in PHP

// WAY-1:

$file_name = "ding.txt";
echo substr(strrchr($file_name,'.'),1).'<br/>'; //Shows ext. eg; txt
echo substr(strrchr($file_name,'.'),0).'<br/>'; //Shows ext followed by a dot (.); eg; .txt

//Auto download all images of an album. 
//Works if the images are stored in sequential order in the server. eg: img-01, img-02, img-03 etc.

for ($i=0; $i <=10; $i++) { //capturing first 10 images. change the max value to download more

$d = 'http://example.com/album/image-0'; //first part of the image uri
$e = $i; //image number
$f = '.jpg'; //img extension
