I first had a phone interview, and then 3 separate in-person interviews. Then I was called back to interview with the CEO. I then had one more 2:1 interview that day.

I was contacted by an HR rep, had a phone screening scheduled immediately and then a phone interview the next week. Despite being told they'd be in touch within a week, I never heard from the company again. My follow up was ignored and when I reached out to ask if they had filled the position with another candidate I never got a response. Overall the process felt unprofessional.
