HR was pretty prompt with their reply after the application. I was sent an online test first, then invited to an interview a few days later. The office was pretty impressive. It's an old-looking building from the outside, but all modern and arty inside. Guests need to wear a photo name badge at all times, or security will get mad. The reception area is the kitchen, with large amounts of free food and drinks.

The interview was 1 hour, 2 on 1. It started with 'Why Bloomberg?' and then went on to C++ questions. I had to write code on paper on the spot. It ended with a logic question.

You have two pieces of string. They are of different lengths and have non-uniform widths. Each string takes exactly one hour to burn.

The remaining length of a burning string does not indicate how much longer it will burn.

A lighter can be used to measure 45 minutes.
