Typical interview process: screening with HM, 3 technical interviews, another screening with the HM. Overall it was okay, except for the interviews with the HM.

For the first one, he was late and hadn't seemed to have read my resume, needing to read it as the meeting started. For the second one, he asked all the same questions he had a week or so before. He seemed unengaged and was asking such highly specific questions about solving their specific technical problems that it made me wonder if the listing is even real at all, especially given how old it was. In either case, he didn't communicate what he was asking well and I was frustrated that it seemed like he didn't understand what I was saying. All the other interviewers were top notch and well prepared.

Typical STAR questions (which by the way, always expect a certain answer, which is why they are widely considered poor and outdated practice).

Don't ask "tell me a time when X" when X is not a usual thing most people will have experienced. You'll just get lies as responses!

And no, you won't be able to tell!
