Yelp Software Engineer Internship interview questions

First I got sent a timed online assessment test that consisted of one question. This was straight forward. It involved arrays and hash tables. This was followed by a technical interview via Skype. During the call I was given another assessment test, this time with the interviewer.

The first step was a very easy coding challenge via Hackerrank. The next step was quick chat via Skype with technical recruiter about my background, opportunities in the company and such non-technical related things. In the third step, there was a technical interview with two quite easy task, which required only knowledge of basic data structures.
