9,111 backend software engineer interview questions shared by candidates

The algorithm questions were standard questions involving arrays and strings, nothing too difficult or that couldn't be trained for. The debugging session was more of a collaborative white boarding session (shared screen on google hangouts) going through a scenario of figuring out why a service was having issues. The engineers running the interview would give a basic outline of the architecture and you would need to ask for more information to get to the bottom of the issue. The systems design question involved architecting a new feature for uploading photos to playlists.

I really enjoyed the selection process! They were very clear with me about the profile they were looking for. They asked me mostly about my experience with ruby ​​on rails and then they gave me a "take home challenge" which was basically an app that connects to the zype api and shows its videos
