I applied online. The process took 2 weeks. I interviewed at UBS (Londra, Inghilterra)
Interview
In total 5 interviews with people from different areas of the investment bank. In three interviews I was given technical questions (math, computer science, machine learning) and some behavioral questions. Overall, grueling but fair process.
Interview questions [1]
Question 1
Q: Describe Q-Learning
Q: Which of these two mathematical expressions is greater
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
