I applied at Snapchat and interviewed via Google Hangouts. I interviewed via Google hangouts. I got every question correct, except for the coding portion where the outcome was to remove 2 return statements and move a comparison operation in front of the base case. My interviewer did not seem to understand very basic CS concepts and I explained to the interviewer that Linked Lists are faster for insertions and removals after he admitted to me that didn’t remember what the merit of using a Linked List was or when to use one. I went above and beyond in explaining the questions and how they related to concepts that I knew outside of what I was asked. So because of that I was told that I gave a sufficient answer during the coding portion, though I was told that it might be good to debug the solution while I was talking to him. I answered their questions very well and explained my thought process and followed the interview process closely, so I didn't see much room for improvement, yet I was still rejected when because I was not "a perfect match in the qualities sought in the iOS Engineering position", which I do not understand at all based on my performance.
