I contacted a recruiter via LinkedIn to express my interest since I had heard about the company and the principles and really thought I would fit in well. I then formally applied to one position but the recruiter I contacted thought I would be a better fit for another job. I was sent the three personality tests that took about an hour and a half to complete, then was contacted the next week to ask to come in for an in person. I was there for 10 hours and had a number of interviews. Other candidates for the same position were in the room with me throughout the first half of the day. First portion was a debate about a hot topic, then a case study, then a culture fit portion. After lunch the other candidates were called out of the room. I never saw them again so no clue if they moved forward or not. Here they told me they were very interested in me and the rest of the day consisted of 1 on 1s or 2 on 1s with hiring managers, mostly about who I am, what I would be concerned about, and if I am a culture fit. I really enjoyed the day. First interview I have ever been to where I truly felt like I could be myself and did not need to sell myself. They are really just interested in whether you are looking to learn and contribute and are a fit with the unique culture they have established. Very bright people. Do not try to present yourself as someone you are not. They will see right through it. And if you are not the right fit, you will be miserable if you get the job anyway. I was offered a position about a week later and given the option to choose what team I'd like to join.
