Quantitative Analyst Interview

Quantitative Analyst
New York, NY

I applied through a recruiter and the process took 5 days - interviewed at Knight Capital in June 2012.

Interview Details – Two interviews. First one with their recruiter, talked about some general things and why I'm interested in finance. The second one was an all-round phone interview with algorithms, coding and probability questions. In the end they did not think I fit the position well.I did not have the calculator handy to calculate the expected reward exactly (see below).

Interview Question – How much would you pay to play this game? You have a fair coin. You get heads you win $1 and can continue to play. You get tails, you collect your winnings ans stop the game.

Second question. Now what if the winnings double each time you get heads.

Electronic Trading Group Interview

Electronic Trading Group
Jersey City, NJ

The process took a day - interviewed at Knight Capital in January 2012.

Interview Details – Interview consisted of several 1:1 interviews on-site. Questions were standard mix of quantitative and non-quantitative. They seemed smart but the interview process was not handled professionally. There was no receptionist and I was not provided information about where in the office to physically meet the interviewer so I had to ask several people around the office. There was a considerable amount of time spent waiting between interviews in a conference room due to poor scheduling and I spent at least 1.5 hours in aggregate waiting between interviews, being told every 30 minutes that the next interview would being shortly. The final interviewer briefly apologized but I was very disappointed with the lack of professionalism.

Interview Question – Standard probability and statistics.   Answer Question

Senior Java Developer Interview

Senior Java Developer
Jersey City, NJ

The process took a day - interviewed at Knight Capital in December 2011.

Interview Details – Went on this interview through a recruiter. I arrived 10 minutes prior, asked for the hiring manager who they seem to have trouble reaching. Finally they told me to take the elevator up arrived at the IT but door was locked. Someone was nice enough to let me in. No sign of hiring manager. 5 minutes later, he comes and gets me. It did not seem like they interview people much since they did not have a conference room or office available to interview. We finally ended up in an office that was like Arizona in the middle of the Summer. The hiring manager asked about experience and asked some technical questions. From the questions, it was clear that they were using J2EE circa 2001... going from JSP/Servlets to Struts 1.x. From there is was clear this job not for me. A lead developer came in looking sloppy, miserable and gave me a dead fish handshake. This was my first interview in quite some time and used it to bone up on interviewing skills otherwise would have walked out.

Interview Question – Some questions on java reflection.   Answer Question

Trading Operationist Intern Interview

Trading Operationist Intern
Jersey City, NJ

I applied through college or university and the process took 4+ weeks - interviewed at Knight Capital in January 2012.

Interview Details – The interviewer was very nice, giving me suggestions and hints.

however it seems we miscommunicated before hand, and i originally was applying for the software engineer intern yet ended in the trading operationist position, which resulted in my expected tragedy...

i was asked various questions on math, like hidden markov model, probability, combinatorics,

and then i guess out of kindness the interviewer figuratively asked me some VERY simple coding questions...

then the interview ended.

Interview Questions

  • how to reduce the number of states in a hidden markov model? (actually i dunno what this question means...)   Answer Question
  • given a dice, you can throw it at most thrice unti you feel satisfied with the number. design a strategy so that the expected value of the last throw is biggest. (a relatively easy question)   View Answer
  • pros and cons of hashtable (very easy, the purpose of this question is only to let me feel not that embarrased)   View Answer
  • unix shell commands like grep diff (very easy, the purpose of this question is only to let me feel not that embarrased)   Answer Question
  • also there are some EXTRA HARD math problems that i can't even remember now....   Answer Question
