Had 2 technical interviews, both 1 hour long with an engineer through Google Hangouts and CodePair (Hackerrank). The interviewers first asked to describe yourself and your projects, and "why Snap?". Then proceeded with a coding question (~Leetcode medium), and after you finished, the interviewer would let you ask him/her questions about the company.

My first interview was alright; my code was quite messy and there was a bug that I didn't end up fixing, but my interviewer said that my solution was good and would work. I honestly thought I failed it, but I was able to move on.

My second interview was much better. The problem was a little more algorithms heavy, and the interviewer guided me more to achieve the best runtime. I was able to get the correct answer and later told him things I would do to improve memory usage further, and he asked me about some data structures that I could use to implement it. He was really nice and told me that it was a good interview!
