Applied online.

One week later, I was invited to take an online IQ-type test. It was straightforward and mostly knowledge-independent. Some basic graph theory helps with a very small number of the questions, but it's not worth spending time on if you don't already know it.

Two weeks after taking the test, I received an email stating I was through to the next round: a phone interview. This happened one further week later. The phone interviewer was pleasant.

It started with general questions about my background, why Bloomberg, and the usual," followed by some technical questions. This interview is about knowing data structures and algorithms, with minimal emphasis on coding. Nothing to be scared about.

Unfortunately, I blew it by preparing for the wrong thing or being nervous during the first interview, so I have no details about later rounds.
