I applied online. The process took 1 day. I interviewed at UBS (City of London, England) in Dec 2010
Interview
A paper-based test comes first, covers programming, probability and stochastic calculus.
Then get interviewed by two professionals, each 40 minutes. Questions are all technical or brainteasers, no behavourial ones.
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
