I applied through a recruiter. The process took 2 weeks. I interviewed at UBS (London, England) in Mar 2024
Interview
Onsite interview in London. Three technical interviews with questions on undergraduate level math, machine learning and statistics. The questions were fair, though some brain teasers from probability theory were tricky. Then two rounds with management and HR.
Interview questions [1]
Question 1
There wasnt a single question that was most important. One of the technical questions were to decide whether a certain convex functions inequality was true
Take home exam on data analysis and statistical inference, and then two rounds technical interviews, mostly probability and classical statistics and machine learning. Some simple algorithm questions done verbally too.
First round was panel Interview with 2 people, Ask questions on Statistics and resume. One was the VP of the team and other was regional manager. The Interview was not that difficult. But then I was ghosted. There was no reply from either HR or anyone else, I tried contacting them several times
