First thing to realize is that all interviews are via video, so best to prepare accordingly. This was explained well in the setup email/calls. I had a preliminary call/interview, followed by (I think) three more within a week to a week and a half (pretty sure it would have been quicker but I was unavailable for a couple of recommended timeslots). Very aggressive but also welcome because I was really...really ready to leave my former position. The initial call was a screening call...I felt that...the whole thing could have ended there so every interaction is critical. This initial call also explained the entire process and let me know what to expect every step of the way. The interviews themselves were pleasant, but challenging. The people you interview with are true experts in every sense of the word and will challenge you. But, then again, I was looking for challenging work so that was fine with me. I never had a doubt as to where I stood...if I was being moved on or if the process was over. There was always a very short (if at all) timeframe before I was told I'd have another interview or not. Having withstood previous interviewing black holes, this was appreciated. I made it through but I'm also aware that those who don't are informed as quickly as possible and treated with respect...always thanked for taking the time out of their schedule to participate. As a quick summary I would say that this interview process was the most professionally conducted I've been involved with (from either side of the table). Knowing so quickly if you're moving on or not is such a respectful thing to do - but many other companies fail to do this.
