one round phone call interview， no behavior interview and failed the technical one，The interviewer is a quant researcher and had a phd degree. Powerful and smart guy . Though fail but thanks.
Got asked very easy questions which I solved almost instantly. Had a good chat with the interviewer because there was quite some time left. Was rejected two weeks later on a Sunday. No feedback at all.

Ho presentato la mia candidatura online. Ho sostenuto un colloquio presso Citadel (Londra, Inghilterra) nel mese di nov 2024
Colloquio
The process contains interviews of 45 minutes, i passed three interviews two of them was with quants and a third one with a software engineer. The interviewrs was nice and the questions was about statistics (linear regression, PCA, regularization...), brain teasers and code (type leetcode meduim) and also the software engineer asked me to code a class (oriented object programming).

Two guys would like to meet at a train station and they will arrive at a random time to the station (between 4pm and 5pm) each one will wait 10 minutes for the other what is th eprobability that they will meet? (the brain teasers was classical ones all of them are in the green book). Good luck and don't hesitate to code a little bit of oriented object programming. (it's because of this i didn't get the offer)
