I had a 1 hour technical phone screen with an engineer from Bloomberg.
First 10 minutes: about the engineer himself, and a bit about myself and background experience. He asked a bit about some of the tools I used in previous projects, and what I liked about them. Very basic and standard.
Rest of the interview was two tcoding questions.
He didn't ask me to compile my code, just wanted the general algorithm and a walk through of how I came to my answer.
Overall a positive experience!
