I had a very unpleasant experience interviewing at AppsFlyer. During the interview, I was repeatedly interrupted and wasn’t given the chance to fully explain my answers. They asked me to draw a system design of a project I’ve worked on, but I barely managed to sketch two components before they started firing off questions nonstop. Despite this, I answered all their technical questions correctly (I later verified them) and even solved the coding problem perfectly. Still, they informed me by email that I hadn’t passed. I made the effort to come to their office and spent an hour and a half in the interview, only to receive a rejection with no constructive feedback. Overall, it was one of the most unprofessional interview experiences I’ve had. I wouldn’t recommend interviewing there.
