Metronome Engineer interview questions

Very lengthy and slowly drawn out inefficient interview process. Around 7 interviews that were poorly organized over the course of 2+ months. Interviews included take homes, take home review .. and even presentations. At one point I was told the next interview was one thing and then the night before was told it was a completely different interview which would require sufficient preparation. I stayed up late to give it my all. They also take a long time to get back to you following each interview. Overall just not at all considerate of anyones time..not a good process and honestly wasn't worth it. Rejected after the final round for a reason that didn't seem that sensible to me... proceed with caution!
