J'ai postulé via un recruteur. J'ai passé un entretien chez Citadel Securities (Londres, Angleterre) en févr. 2024
Entretien
I only got the the screening round, but there would have been 2/3 rounds after this including LeetCode style questions and meetings with the manager. I think the further rounds would also have technical components regarding ML (my background) as well as basic maths.
Questions d'entretien [1]
Question 1

Follow up: now what if you have N - 1 fair coins, and the Nth coin is not fair, but lands on heads with probability p?

It was mostly about coding. I was first being asked to share my research experience followed by a Q&A, and then we moved on to a DP problem. Since we discussed my research for ~ 40 min, I didn't have time to finish testing my code.
