Niantic interview questions

I applied online. I had interviews with hiring manager, multiple designers, product manager, director etc. There was a take-home assignment that took me days to complete and a whiteboard design challenge in an interview with a designer. One of them's attitude was not great and I got offended. The process was too long and it took a lot of my effort.

Interview process consist of 3 rounds of interviews (each with a design lead, product lead, and eng lead) 2 white board challenges, and 2 final interviews. The entire process took about 3 weeks.
