I went through a initial round with the HR and scheduled for 1 hour initial phone screening.
He was a product manager who called started asking the right away on what my favorite product. It could be anything I use in day-to-day life. Then, he asked to define the problem statement and asked to go through fundamental stages of defining a problem. It was very basic actually that you end up being nervous. The interviewer were very straightforward and only wanted to hear particular answers.
Very self-driven, first of multiple rounds, where I had to take the initiative to arrive at the problem, constraints, approach, solutions, tradeoffs and reasoning behind it in a matter of 30 minutes.
Overall a lot of steps to the interview process. Talked to different people and had opportunities to ask questions. Many different stages which made it a lengthy process overall. Wasn't too bad.
You would have to do a hiring assessment first, then a recruiter screening follows. First round interview with the hiring manager. Majorly product sense and product improvement. The questions were not direct though.
