I applied through a staffing agency. The process took 2 months. I interviewed at Two Sigma (New York, NY)
Interview
OA + 4 round virtual onsite (3 coding + 1 design) + team match (including BQ here) + conversation with the director (basically a skip manager).
I matched with 3 teams and a team manager was really interested in me, but the last conversation with the director failed, and the recruiter refused to provide any feedback.
Overall the process took two months. The fact that after such a long process there is no feedback is rather frustrating. I would not recommend applying here unless you truly want to get in. It's unclear what the hiring bar is and obviously the final boss can just reject you

first interview was 60 minutes long with a leetcode hard question. second interview was 2 back to back 60 minute leetcode hard with emphasis on data structures. each interview had a 5 minute introduction and 10 minute at the end to ask questions
Standard medium difficulty hackerrank. The question involved decoded an encoded string. It was not something I had seen on LeetCode before and I think was unique to the company. The question was not that difficult but I ran out of time right before I could finish answering.

Decode a string encoded using a specific encoding algorithm.
It started of with one phone screen, then if you pass you have 2 back to back technicals, then 3 1 hour behaviorals, hiring committee, and management committee. Standard Leetcode and behavioral questions.
