J'ai postulé via un recruteur. Le processus a pris 2 semaines. J'ai passé un entretien chez Optiver (Londres, Angleterre) en nov. 2022
Entretien
The interview process starts with a quant trader test which is roughly a psychometric / fast mental maths or being fast with a calculator (which is allowed). I did not make it further : I certainly did not expect this type of test nor prepared for it. It is very bizarre for a process for StatArb quant researcher job to have this type of test (no probas, no stats, no ML, no finance, no algorithmics) which would be totally expected for a quant trader role, however.
Questions d'entretien [1]
Question 1
Train on speed : 24 questions on 36 minutes, you can be a good mathematician/statistician and not get past the threshold. For the first round, you will not be asked anything to do with probas, stats, ML, finance or programming / algorithmics.
Online assessment including Hackerrank. After 2 months I received an invitation for a HR round (the classic stuff), then a technical round, take home assignment then final round split into technical then HR.
Online assessment with 30 timed multiple-choice questions. You have a minute and half for each question, Once the timer runs out you can't go back to that question. A big portion of the problems involve random walk. Some questions require an exact solution, and some are estimates.
A long and exhausting OT of a few sections. Then some interviews on standard green book questions. In between one HR interview. Final round on a take-home ML project. Overall nice experience and HR provides feedback throughout all interviews.
