WorldQuant interview questions

I was head hunted by a company employee at an open day at my university. after a long conversation about his position and work I offered some of my knowledge in the filed. He was quit impressed and asked for my CV and grades list. I received a phone call from the company where they said I was right for the position. I was asked to take a 90 min online quiz that has almost nothing to do with the job position I applied for.

First,sent my CV to HR 1.written test 2.on site interview 3.phone interview all of them are brain teaser and probability. I thought I answered all of these questions. The hiring process was tooooooo long, I waited for about two or three months, they should know not anyone can waste time only for their special recruiting process, so I declined the offer when they come to find me. By the way, Salary is not attractive compared to other software company, if you want to grab some talent people, you should speed up your step and don't regard them as nothing.
