The process took 1 day. I interviewed at UBS (New York, NY) in Feb 2009
Interview
Spoke with them at university's career fair, got a call the next day for an on campus interview. The questions were straight forward, coding stuff: interpreted vs compiled, what is OOP, what is polymorphism. Then they ask a little about finance: what are stocks, bonds, etc. I didn't go into as much detail with the answers as I should have, it's good to show enthusiasm and knowledge for everything you answer.
I joined for a junior role and the interview process was very straightforward. First step was filling some online forms about general fit. Then a technical interview over Teams - no live coding was involved, only questions about my past experience, the technologies I worked with and how I would solve problem xyz. After that it's straight to manager interview and decision.
Interview questions [1]
Question 1
Give a detailed overview of how you would design a pipeline for streaming large amounts of data and reduce the risk of throttling or failure.
Group interview with 2 other people. They give us a problem, allow us 15 minutes of prep time, then each will sequentially get access to a keyboard to code for 10 minutes. After the code, each person is asked about what went well and what could be better
Made it to 3rd round.
1st round -> Aptitude Assessment
2nd round -> Hirevue
3rd round -> Mob Programming
Didnt make it past the mob programming session, (mob programming includes a group coding session where you and two other candidates work together to solve a problem)
