Complete clown show. They front load the process with a take-home case, run you through a lengthy loop of 4-5 meetings, and then the micromanaging CEO and his zero-EQ robots insert themselves into the process and hijack the application with additional arbitrary rounds (one with the CEO himself lol!) where the real discrimination likely happens. Read the employee reviews - the product org at Apollo.io is probably the most confused and inferior in the industry. Before going through this process, imagine trying to exit this company when everything you've built and all decisions made (the entire PM value prop) were forced on you by some autist and his servants. They had over 10 PMs voluntarily resign recently. It checks out from the outside.

Interviewed for a Sr. PM position, made it through all rounds but did not get offer at the end. The process was great though. Recruiter kept me in the loop the entire way through. No take home assignment. Spoke to hiring manager, then had 2 virtual on sites with 3/4 folks in each round. There were two case study questions of 45m each.
