Trading Intern Phone Interview with Jane Street. What to expect?

I have a phone interview with Jane Street for a trading internship. I don't have a finance/economics background, but computer science. The website said it was fine that I don't have a finance background, but still worried.

As far as I know it is heavy in statistics, but what level can I expect? Would second year stats at university do?

Has anyone been through this? Thanks in advance.

Jane Street is extremely quantitative. Also expect brain teasers, especially numerical ones: for example, given a 5-digit number with 2 repeating digits, how many ways can you permute the digits to arrange a strictly ascending integer sequence? Be able to do long division & multiplication in your head.

Years ago when I was in this interview process, I got nearly everything correct except 1 or 2 "hard" number teasers (my interviewer would confirm when my answers were correct) and didn't pass the 1st round. This was for FT, not internships...and there were supposed to be at least 5 rounds (yikes)
