I applied through university. The process took 1 week. I interviewed at TransMarket Group (Chicago, IL) in June 2012
Interview
I just finished the first round phone interview and was asked 4-5 mathematics/statistics questions.
Some of the questions are really hard. I messed up with one question but still get the second round.
Interview questions [3]
Question 1
What the probability of getting 2 consecutive heads in a total of N tosses (I found this one pretty hard and I didn't figure out the right answer at the time.)
