Le processus a pris 1 jour. J'ai passé un entretien chez Jane Street (New York, NY) en avr. 2011
Entretien
Asked about past research projects I've worked on. They chose an interviewer who was well qualified in my research field. (I guess they pass down your resume to their employees, and whoever has experience on things listed on your resume is your interviewer). After that, asked me statistics questions, and some computer science questions.
Say you have a list of numbers, how would you output a list that eliminates repeating occurrences of the numbers? What is the time complexity of the method? Can you do better?

Question 1
Brain teaser . depend on how you answer the first question.
Go to a bar, throw darts for 500 times, 1/2 probability hitting the target, 1 point awarded for each hit. Now getting drunk and throw for 500 times, 1/2 probability hitting the target but 3 points award now. (1) What is the expected score/number of hits? (2) If we got 1100 points, give a feasible (say 15 points) interval estimate of points? (3) How to make this calculations exact?
