I applied through college or university. I interviewed at UBS
Interview
I had three rounds of technical interviews. The first round is to solve some stochastic calculus problems.
The second round is with 5 interviewers, they asked questions based on what you have learned before or your experience, I've been asked about Black Scholes model, Vasicek model and how to solve different SDE.
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
