I was really excited to interview for this company, I really liked their mission and products! Sadly, I was really disappointed in how it all turned out. First was the initial phone screening with the recruiter which was great, then there was an hour-long technical interview, and later another hour-long interview which was a "brainstorming session." Lastly, there was a day-long set of interviews -- In the first of those, I had to present analysis and findings from a prompt & data set they had given me a few days before. They said to spend two hours preparing, but that would not have been enough so I spent quite a bit more time on it. The remaining three interview for that day were a problem solving session, another brainstorming session, and a wrap-up session where I had an unexpected second interviewer ask me a random statistics question. It was the most rigorous interview process I've ever been through. Looking back on it, I didn't feel like those interviewing me cared much about me as a person... I was never asked a single personal question. It seemed like a very intense environment. I was never offered the position despite making the final round of interviews. After all of the hours and effort I put in (not to mention I took an entire day off of my current job), I never even got a reply from them -- radio silence. I followed up a few times to no avail. I just find it to be incredibly cold, disrespectful, and unprofessional. I think I am glad I didn't receive an offer knowing all of this. I know the people there are very smart and great at their jobs, but the lack of basic decency and interpersonal connection just didn't do it for me. I hope my experience was just a one-off and no one else experiences this, but I can't be sure!
