For the interviewer test I got one medium question: a) painting with true price x between 0 and 1000, you place a bid b, if you're below you get nothing/lose nothing, if you're above you pay b to buy it a you sell it to a friend for 1.5x, what's your bid b? For the second question I got a question I found on Jane Street's glassdoor, maybe it's a classic but I didn't prepare for it: You begin with $100. You flip a fair coin. Heads, you get 1$. Tails, your money gets inversed (i.e. first tails, your money is now 1/100). What is the expected value after 10 flips?
