I applied for the position through a referral system set up by my boot camp. Once I applied, it was about a month before I heard from them. UBS is an extremely large company, so this wasn't surprising. I was called by an HR employee who set up my interview. I interviewed with two senior developers, and it was an extremely technical interview. About 5 minutes of get-to-know-you questions, and then about 55 minutes of whiteboarding and answering basic questions about Java.
