Experience:

The interview process for this Quantitative Research Intern position involved an online assessment followed by 3-4 rounds of technical interviews. Each technical interview round focused on several probability questions, with the difficulty increasing as the candidate progressed through the rounds. An example question cited was the classic Monty Hall problem: "There are three boxes, one of which contains a prize. The host opens an empty box and asks if you want to switch or stay with your original choice. Should you switch?" The overall process took 1-2 months, but the candidate did not receive an offer.
