In total I did five (!) separate video interviews, plus a four-hour-long written assessment. A month and a half after the assessment, I was finally asked to do yet another interview (!!), which I declined. In my opinion the process was just unnecessarily stuffy and bureaucratic. Also worth noting: one of the higher-up K2 interviewers was pretty disparaging of the role, and said they doubted that I would enjoy it. I found this to be an odd (if not somewhat rude) thing to say to a candidate. All that being said, I spoke with some pleasant people during the process. It seems like the team is made up of very intelligent people who take their work seriously.
