I applied through university. The process took 3 weeks. I interviewed at Huatai Securities (Beijing, Beijing) in Mar 2018
Interview
First, the employer asked some questions on probabilities and brainteasers. After that, interviewees met together to do self-introduction and then were divided into groups to discuss several non-quant topics. Finally, every group chose one person to summarize.
Interview questions [1]
Question 1
A person’s birthday occurs on a day i with probability pi, where i = 1, . . . , n. Assume independent assignment of birthdays among different people. In a room with k people, let Pk = Pk(p1, . . . , pn) be the probability that no two persons share a birthday. Show that this probability is maximized when all birthdays are equally likely: pi = 1/n for all i.
First round is HR; second round is technical, third round is technical, last round is also technical. Every round asks question about Python, modeling, financial knowledge, etc. Not very difficult.
