Exactly. In Asia they use numbers for their ticker symbols instead of letters. So 120 stocks is feasible. For example: A1, A2, A3, B1, B2, B3...etc
Nice! You're hired! Years ago I was asked in an interview for a floor trader position to estimate the number of windows on the Sears Tower outside the window. And to estimate the number of dentists in Russia. Like 5yrtrader said, they were just looking to see my thought process in arriving at an answer. I really have no idea how many patients a dentist typically has, but I made a stab at it. I got the job but took a different offer from Monroe Trout instead. Aaron Schindler Schindler Trading
I don't mean to split hairs, but the original question didn't ask anything about feasibility, nor did it ask anything about alpha-numeric symbols.
i bombed a question at Goldman Sachs in a very late stage interview (maybe 6th or 7th interview) for a position on the floor of the NYSE.:eek: how many right angles on the clock during the day? i'm a retard. my answer. 'are you serious.' it was my first big interview out of school. then when i realized he was dead serious i panicked and couldn't think. i performed poorly in 1 or 2 of the other interviews, so prolly not the only reason. oh well, things worked out better anyway.
I would say the answer is 48. There are 2 right angles on a clock for each hour of the day times 24 hours.
