I applied through an employee referral. The process took 1 day. I interviewed at UBS in May 2010
Interview
HR contact me several days before to fix the date for the interview, and i talked to two people in turn during the process of the phone interview. it took about an hour. we first went through my resume and he asked questions about my background, and then they described the job roles.
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
