The first stage is an online assessment. After that for interviews, it was one initial interview with a case study, then a day of 3 in person interviews. If you pass the first 2, you move on to the third.
Interview questions [1]
Question 1
Questions based on what you had to study for the interview, but in the context of using that information in a way that relates to something you might be looking at for the company.
I have only done the hackerank so far and got a first round. From my research, the interview process can consist of 1-2 Zoom interviews before an in person superday which typically consists of math (business case), technical, and a behavioral round.

Question 1
Probability (regarding cards) and a lot of order book questions.
It was a case on how to improve Lyft. There was also a math competition question similar to those found in AMC. The question came first and then the case.
