I'm rating this experience negatively because after five interview rounds, a take home assignment and a phone call from a recruiter saying I passed and they wanted to make an offer-I got a follow up email two days later that said they were going with other candidates. They also told me I would only have one technical interview and I ended up having three, so I was lucky I was well prepared. The interviews themselves were nice enough, covered basic statistics and marketing analytics (A/B testing, SQL and R, a case study) but their team is disorganized and just plain sloppy. I'd recommend asking the recruiting team a lot of questions and keeping them on their toes because it seems otherwise they will be careless.
