Quantitative Research Intern Interview Questions

3,500 quantitative research intern interview questions shared by candidates

1)X,Y are standard random variables, the correlation is 0.5. Given X, what's the conditional distribution of Y? 2)A,B,C are r.v.s. correlation between A and B is 0.9, between B and C is 0.9. is it possible that A is unrelated to C? 3)Given two assets, their average return, variance of return and correlation. Find a portfolio such that the sharpe ratio is optimal. 4)toss coins consecutively, get 1 pt if head is up and 2 pts if tail is up. So we can get a sequence of total points. Question: what is the probability that we have 100 pts in this sequence?
