The process was straightforward. There was a recruiter call, which went well. A phone screen with 2 leetcode medium questions. After that, an onsite with 5 rounds - 1 product, 1 behavioral, 1 coding and 2 ML rounds. The interviews ended on a Friday and the following Monday morning around 8AM PT the recruiter sent a note saying that they were planning to not move forward. They lied that they did a debrief, which given the timeline would have been impossible, unless people were working over the weekend. I think the recruiting team at Pinterest is deceitful and gives bogus feedback, rejecting qualified candidates.
