Very difficult and many logic exercises, and it is very difficult to get in. I do not recommend. Little code required, problem-solving activities, many requests and few open positions.

Very positive experience. There were five technical interview rounds, including one systems design interview and a lunch with an interviewer. The interviewers were very knowledgeable and nice, and they helped me feel at ease during the interview.

Standard LeetCode. Seven rounds in total because I got misleveled and needed to take an additional onsite. Overall, a bad experience since I told the recruiter from the start that I was only interested in the upper level of the two.
