**Interviewed null -1**

It was a similar process to what others have already described. You have to be ready for the types of questions they will be asking, otherwise you should probably wait on that interview. It's not very hard to get the initial interview, but keep in mind that you'll go through progressively harder interviews.

**Interview Questions**

Similar to what others have stated, make sure you know basic probability, combinatorics, and can do these in your head.

**Answer Question**

**Interviewed Nov 2013(took 1 week)**

Submitted application for a winter internship through the company site, HR emailed to setup a phone interview a little less than a week later. Interview was purely quantitative, started off relatively easy (mental math, basic probability that you have to answer in 30 or so seconds) and eventually interviewer moved on to more difficult probability questions. You'll be asked to not use your computer/a calculator at all, but the interviewer will walk you through the more difficult problems if you get stuck. Nothing technical/finance related.

**Interviewed Jun 2014 in London, England(took 4+ weeks)**

Applied online and got a reply by mail within 10 days.
First round : Excel task. Check a series of trades on a spreadsheet.
Second round : telephone interview (20-30 min) : Same kind of questions as the one you will find on Glassdoor, mostly mental math, brainteasers and probability. No pen or paper.
- 200,000 minus 222
- Probability of a 3-3 tie on a 7 game series.
- Today is Friday what is the day in ten years time
- The outside of a cube is painted black. It is then divided into 27 equally sized smaller cubes. If a smaller cube is selected at random and thrown on the floor what is the probability that all five visible faces are NOT black?
- Angle between minute hand and clock hand at 9:30
Third round : programming task. Write a program to process a text file with trading data and output a file with PnL for each security on the file.
Fourth round : telephone interview with a trader (1 hour). Problem solving :
- Two spies have to meet. Each one will arrive at a random time (uniformely distributed) within a 1 hour interval, and stay for 10 minutes. Calculate the probability that the spies actually meet.
- Three cowboys A, B and C have a truel (like a duel but with 3 people). A has a 1/3 probability of shooting his target. B 1/2 and C 1. Each one will attempt to shoot the cowboy who is still alive with better shooting probability. A starts the shootout, then B and C (if still alive). Calculate the probability that A wins the shootout.
Fifth round : telephone interview with a trader (1 hour). Problem solving :
- Design a betting system on a 7 series game beetween two teams A and B (even odds at each game), such as if A wins the series your cumulated gain is exacly £100 and if A looses your cumulated loss is exactly £100.

Basically, they want to know how much math you're able to do, quickly and efficiently. Knowledge of expected value is a must, as is basic computational skills. You don't necessarily need to be able to think outside of the box, but they're going to want to see exceptional problem solving ability.

**Interview Questions**

You are given a die with 100 sides. One side has 1 dot, one has 2 dots and so on up until 100. You are given a chance to roll the die and, however many dots come up, you can choose to (a): take that many dollars, or (b): pay $1 and roll again. You can continue to reroll as many times as you see fit, but you only keep the money of the one roll that you choose to end with. What is the optimal strategy and expected value?

**Interviewed May 2014 in London, England(took 2 months)**

3 phone calls, then on-site interviews (also three). Questions vary: some algorithm questions, also design questions and questions involving functional programming (I would tell it is not such important to know OCaml, but concepts of functional programming [monads, types, tail recursion] - I would tell that it was not "basic" functional programming, but these more difficult concepts). Everyone is professional, it was easy to understand what they are asking and you can ask questions to get clarifications.

**Interview Questions**

Two of the interviews had algorithm questions, other two had design questions, one functional programming interview and one coding interview.

The outside of a cube is painted blue. It is then divided into 27 equally sized smaller cubes (like a Rubik's cube). If a smaller cube is selected at random and thrown on the floor what is the probability that all five visible faces are NOT blue?

Contact was made by e-mail to setup a phone interview. Interview was extremely quantitative, but relatively obscure. Main question was about a complex probability game that the interviewer expected you to calculate mentally. A few more obscure technical questions (as a person coming from a math background) and the interview was over. Process seemed self-defeating as a very small number of people would have the intuition to quickly do a problem like that in their head, but that says little about skill.

As mentioned above, a probability game between two players was given and it involved a complex card game requiring combinatorics.
