I applied online. The process took 4 weeks. I interviewed at Two Sigma
Interview
Response was really fast. It is relatively easy to pass the phone screening process and get on-site. But the onsite was very hard. Need to mention that HR was quite nice and the on-site arrangement is satisfactory.
Interview questions [1]
Question 1
The technique challenge questions are not that difficult compared to other IT companies. But it requires clean, bug-free and timely coding. The on-site part could end up earlier than planned if you don't perform well.
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.

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.
