I applied online. The process took 4 weeks. I interviewed at UBS
Interview
In person meetings with technical interviewers and with hiring manager and recruiter, asking about technical aspects of quantitative finance, and work experience.
The process was well structured and organized, with clear expectations at each step.
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
