The process started with a quick phone screening. The usual walk me through your background and tell us what you're looking for questions. After that, I met with three people onsite to talk more about my background, answer a couple of technical questions, and discuss what I would be doing at the company. The second interview lasted about 2 hours, and the people I spoke to were very polite. After this, I was given a take-home data exercise and was asked to schedule a presentation sometime next week. At this point, things got strange. Every time I tried to schedule my final presentation I was just told that they had to hold off on next steps. I wasn't given a reason for the delay and I wasn't given any indication of when the interview process would resume. After this happened 3 or 4 times, I just found this behavior so rude and unprofessional that I had to withdraw my application from the company (which I have never done before).

Contacted by recruiter; went in for an onsite behavioral; got a data assignment, ended up presenting it about a week later. Didn't receive the offer, but ended up getting a generous amount of feedback from people who definitely made sure you left feeling like your time there was worth it. This is probably the best interview experience I've ever had out of any company.
