Two phone interviews, a take-home assessment, and then a panel interview with about 7+ people spread over two days.

It was a lot more tedious than most other places I have interviewed.

The panel interview part was where I nearly bailed because I had already spent 10 hours on the assessment, and then they expected me to sit through about 6 hours of more interviews for the panel portion.

I understand different departments and roles wanting to make sure a candidate checks out for different reasons, but this process was very hostile to the interviewee's time and energy, especially if they had not given an offer after all of that effort.

I don't think it's worth their time either if I'm being completely honest.

This is the first company I ever did a take-home assessment for that my eventual interviewers actually read through. So, props for meeting regular expectations at the very least.

The interviewers themselves were kind, but tough and fair on the interviewing questions.

I would add that I have never heard of a "culture interview" before, and that name scared the hell out of me.

They should really call it a "don't be a jerk" interview or a "will you get along?" interview. Hate that we call basic decency a culture.

Suppose you had a fairly standard, modern pub-sub event-driven system. Where would you prioritize testing?
