I had two calls (both behavioral) and then a take-home and an onsite. Everyone was super helpful and very nice throughout the process, they were super accommodating and definitely tried to make the onsite be as non-intimidating as possible. It was very conversational, not trying to trick you, you trying to get a sense of how you think. A lot of room to ask questions and figure out if it's the right place for you.
They were able to move quickly as I was in the final stages of the interview process with a couple of other companies, even though it was right in the middle of the summer. They were also super responsive after giving me an offer and made sure I had all the information I need to make a decision.
Overall a great process and a very impressive product.
