Absolutely stellar interview experience. This was the best interview experience I've had by far, and I've interviewed for SE Intern roles with tons of companies. I was invited to interview after I attended one of their events in SF. The recruiters were quick, personable, and very helpful. They would provide documents that helped prepare, answer questions, and give insights on what next steps looked like. The engineers were all incredibly kind. They are super helpful working with you to craft a reasonable solution. They also had a unique style of interview where you could Google/StackOverflow/read docs to your content (except actually googling the question, of course), and you would work through a question together. The level of difficulty was not easy, I would say difficult but fair - there's a lot of help and collaboration to get through the questions. The whole interview pipeline was incredibly well structured, and everyone there is very obviously smart and passionate. Process: - Phone screen w/HR - Phone screen w/Engineer [Onsite in Palo Alto, but they've since moved to Redwood City] - 1 Whiteboard/Laptop standard technical round - 1 Collaborative Online technical round - 1 Behavioral and Cultural round - Lunch and Guest Speaker They also held a meet-and-greet before the actual interview date where you could engage with interviewers at an off-site location, which gave you a chance to be personable with the team and meet the people you'd talk to in a low-pressure environment. Also got to say hi to Priscilla Chan!

I did the interview on karat. I met engineers from karat on a video call, they don't work for czi, they just do interviews for them. The interviewer was very nice and helpful often giving tips.
