I applied online. The process took 4 weeks. I interviewed at UBS (Londra, Inghilterra) in Feb 2023
Interview
Technical interview: Programming, Coding, Mathematical, and Finance questions. It lasted one hour and a half. It was with three people together. It was a remote interview and the interviewers were polite and well prepared.
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
