It's a gauntlet of interviews, but I had a ton of fun doing it! Started with an HR screen and then they had me take an aptitude test (forget which one). I did a kata with a senior SE and then talked to four or five more people including my would-be lead. I liked everyone I talked to and was able to get a good sense of the culture and vision. When they matched my competing offer I was sold!

First interviewed with one employee about basic resume information, then was given an aptitude test. Received a follow up interview with two different employees, going more in depth about the job and its requirements.
