For this position, indeed has an interview process of take-home assignment -> phone screen -> onsite. It took two days on the take-home assignment, and THREE WEEKS to hear the feedback from indeed. Three weeks, sometimes they say they are working on the review, sometimes the reviewer is on vacation. The feedback is no good. They refused to provide the reason. However, they recommend another position to me, and during the communication with the other recruiter, I learned that one person just transferred to the product scientist team. I kinda suspect the real reason of the unreasonably long take-home assignment review.

During one interview, I remembered that I was asked to solve a real-world problem related to the role. Explaining my thought process confidently impressed the panel, leading to further questions.
