Colloquio
I had a 30 minutes interview. For the first 20 minutes I was asked to solve mental math problems and brain teasers. For the last 10 minutes or so I was allowed to ask questions about the company.
Some questions:
1. What is the sum of all the odd numbers form 1 to 100
2. In an urn you have red and blue balls (same number of balls in each of the two colors). You extract 3 balls what is the probability that the number of balls you have extracted is odd. Now you extract 10 balls, what is the probability that the number of balls you have extracted is odd?
3. There are 30 blue and 30 red balls and two urns. You play a game. Your opponent has the right to arrange the balls in the two urns as he pleases, without telling you what he did. You then must draw a ball from an urn of your choice. You win $10 if you draw a blue ball, otherwise you get $0. How much would you be willing to pay to play this game?

Colloquio
Some brain teasers and probability problems that are variations of commonly seen quant interview problems. Require smart reacting rather than very high level maths or finance knowledge. Friendly interviewers, active involvement.
The interview process involved multiple rounds, starting with a phone screen covering probability, brain teasers, and market-related questions. This was followed by a technical assessment focused on programming and mathematical problem-solving. The final round included onsite interviews with case studies, logic puzzles, and discussions on trading strategies. The process emphasized clear thinking, structured problem-solving, and strong quantitative skills.

Zoom interview, The audio quality is very poor, and I find it very difficult to hear the interviewer's speech clearly. They asked a question about probability. Zoom interview, The audio quality is very poor
