Datadog Product Manager interview questions

Speedy- 3 rounds. First round is a simple phone screen. Second round was a technical discussion with an engineering manager. The third and final round was a 4 hour super interview, 1 hour with a fellow PM going through a case study (aka full product lifecycle), 1 hour going through a system design case (use YouTube/ exponent to study) this one is very technical, and 1 hour break, 1 hour on strategic questions (employee interviewing noted that they hated Datadog, was a very uncomfortable hour), final hour with an engineering manager going over more of a resume review and how you work with engineers. Did this super day, did not get the offer. I asked HR about their gender breakdown as well as I asked the fellow female PM that I interviewed with, both HR and she noted that they are working on it, but it’s pretty bad.
