Onsite interview was a series of 6 meetings with data scientist, architect, PM, engineering manager, CTO, and HR. CTO is super cool to talk to. HR is a heavy cultural interview. Many others talked about interest in the role and the company and what would be involved. Briefly discussed how I would approach a scenario to detect malicious activity with some sort of ML approach. I didn't get much time to ask questions cause the questions I was getting asked kept going over time.
