J'ai postulé en ligne. Le processus a pris 2 semaines. J'ai passé un entretien chez Five Rings (New York, NY) en sept. 2025
Entretien
OA with difficult quick math and stats questions. Each question is like 2 min so need super fast reaction. Then there will be several rounds with difficult tech questions, mainly about math algorithm and statistics.
Questions d'entretien [1]
Question 1
A classical question about dice: expectation of two 1 in a roll.
Hackerank OA which asked a series of maths problems. Very time pressured. Not standard probability or EV problems, more misc maths questions. Didnt get past this round, definitely the hardest OA i've seen.

The first round consisted of a resume screen then a hackerrank round consisting of quickfire math questions, basic calculus, and moderately difficult statistics questions. I did not pass this round.
