Cracking a coding test interview

Coding interviews are always for me an opportunity to learn and grow which is why I wanted to share you my thought process for this one I found this morning at letsrevolutionizetesting.com

What I saw when I visited the page home page

I revisited the application form application_form

I wanted to know what technology was used for this server discovery

I was happy to find out it was ruby

And the hint was suggesting I should try json and I did. If you know ruby on rails then it comes to you naturally request

But now I am in front of the page with this json payload. It says follow so I followed the link. Once... request id json

Twice... request twice

Then I said wait... but wait...

It was too good to be true. So you have two choices:

  • either you go follow one by one the id chain
  • or you can just write a bit of function like I did Alt Text

On the last page: The holy grale result

You could have go for an iterative version with a loop

Wrap up

I guess at RainForest they will have to make a new test since you know the answer for this one. Overall I think it way simple enough. We just needed to take each problem one at the time and yeah every beginner can do it too.
