Jane Street (Quantitative Trading)

quantnet.com will probably be able to more effectively help you.

Just go to glassdoor and browse the questions on this sites company database. Similiar interviews at Susq, five rings, and to a lesser extent Optiver, drw, etc. Lots of math brainteasers and probability and such. If you are not a "math" guy, don't sink too much time into this, you won't get the position.

Thanks everyone!
