Longest interview process I've ever experienced. I was told this is very standard and this one was looking for someone fast(I don't think this was true): 3 separate 1 hour phone screens over the course of 2 weeks: 3 hours total. 1st was very technical. 2nd and 3rd was kinda casual but still long with different individuals. The in-person interview was 4 hours long....this was normal procedure. Instead of a normal panel interview, they actually have you meet with the heads of the company and some team members: Individually, Who ask the same standard interview questions and go over your resume the exact same way. This is rather annoying and by the 3rd or 4th hour, VERY tiring. They're not very critical(unusually positive) but it is very, very repetitive. I couldn't tell if they were just super nice or already had a contract waiting for me to sign at the end. I promptly received a "no offer" response the next day without any explanation. I get the impression they're very picky and hire rarely(4/5 of interviews on glassdoor are "no offer", was repeatedly told they spend a lot of time vetting every candidate the same way). If you're under the assumption(like I was) that they pretty much decided to hand you the job after spending so much time speaking positively about your experience and how you would be an asset without being very critical or expressing any worry: don't believe the hype! It's just standard procedure from what I was told. If you get offers from other companies like I did before HS2's slow process finishes, take them.....don't hold out like I did. I've never interviewed with a company that seemed so eager to pump you up and make it seem like they're courting you. This wouldn't be so bad if they didn't waste 7+ hours of your time and call up all your references or at least compressed the time frame(1 week delay between each phone screens and interview). Office is nice but very far on the north side: FYI
