First step was 3 hours 15 mins on Codility without even a HR screen. Sheer length of questioning demanded a lot of time commitment to say there hadn't even been a process briefing. This felt really unwelcoming and demanding so I didn't follow up.

I applied online. The process took 4+ weeks. I interviewed at Maven Securities in October 2020.

Interview

Applied via LinkedIn. Got a questionaire a couple of weeks later to fill my legal status in the UK. A couple of weeks later was invited to complete the online assessment in 3 parts. Did not make it past the first part. First assessment is about 60 questions where you get around 10 seconds to answer. Right answer results in 2 points and wrong answer results in -1 . Need to be extremely quick and accurate. This is hands down the hardest assessment I have ever done for this type of role. Not sure if this is passable for ordinary mortals, unless cheating of course and using a calculator. Involved mental arithmetic and sequences.

- (2nd round) Wes is building a toy tower. He has a bag with 6 blue blocks, 6 green blocks and 6 red blocks. He picks a block out of the bag at random and places it down. He picks again, but this time placing it on top of the previous block. He repeats until his tower is 5 blocks high and then stops building. What is the probability his tower consists of exactly two colours? Answer is 65/238. [Please practise with this question because there are 3 different questions with the same core - just the final part changes. Be good at combinatorics!] 2 Answers
- (2nd round) Alper is the owner of Cube-XYZ, a perfect cube-shaped planet, and builds a mansion on one vertex of the cube, and distinct houses on the seven other vertices. houses are considered next door if they are connected by an edge of the cube. He is to host an intergalactic tea party for his friends: Wes, Ethan, Henry, Alan, James, Vincent, and Tom. They are able to be accommodated in separate houses. As host, Alper has conditions on how the guests must be placed on his planet:

i) His best friend Ethan must live next door to him.

ii) Henry and James must not live next door to each other.

iii) Alan and Vincent must live next door to each other

iv) Wes should be as many edges away from Alper as possible

v) Alper lives in the Mansion

vi) Tom lives (strictly) closer in distance to Wes than Alper.

i. Given all conditions are met, how many combinations of living arrangements are there? Possible solutions are: 24, 36, 45, 48, 64. 1 Answer - (2nd round) Alper is the owner of Cube-XYZ, a perfect cube-shaped planet, and builds a mansion on one vertex of the cube, and distinct houses on the seven other vertices. houses are considered next door if they are connected by an edge of the cube.

iv) Wes should be as many edges away from Alper as possible

v) Alper lives in the Mansion

vi) Tom lives (strictly) closer in distance to Wes than Alper.

ii. Suppose instead there are two non-intersecting tunnels. One is between the mansion and the house diametrically opposite, and another between a different pair of diametrically opposite houses. This makes the connected houses 'next door'. How many possible living arrangements are there now? Answer Question - (2nd round) Alper is the owner of Cube-XYZ, a perfect cube-shaped planet, and builds a mansion on one vertex of the cube, and distinct houses on the seven other vertices. houses are considered next door if they are connected by an edge of the cube.

iii. Given the conditions in part ii are met (i.e. look at my previous question), what is the probability that Ethan and Wes live next door? Answer Question - (2nd round) Andy and Marjorie are playing tennis. The points system is as follows: there are two conditions for a player to win a game:

1) A player must reach four points in that game before their opponent. So for example, if Andy wins four out of the first five points, then he wins 4-1.

2) A player must have at least two more points in that game than their opponent. So for example, if the score is 3-3 and then Andy wins a point, then the score is 4-3 to Andy but the game isn't over. If Andy wins the next point, then he wins the game 5-3; otherwise, the score is 4-4, and again a player must win two points in a row to win the game.

When the score in a game is tied at 3-3 (or 4-4, or 5-5, and so on), it is called 'deuce'.

To win a set, a player must win six games before their opponent and as with games, this must be by a difference of two. So for example if Marjorie wins 6 out of the first 8 games, she wins the set 6-2. Unlike games, however, sets do not go on indefinitely. You may assume for now that once the set reaches 6-6, it ends in a tie (so no 'tiebreaker').

i. How many ways are there for the score in a game to reach 4-4 from a starting score of 0-0? Answer Question - (2nd round) Andy and Marjorie are playing tennis. The points system is as follows: there are two conditions for a player to win a game:

You may assume for now that once the set reaches 6-6, it ends in a tie (so no 'tiebreaker').

ii. Suppose that Andy has a 25% chance of winning any given point, and Marjorie has a 75% of winning any given point. From deuce, what is the probability that Marjorie wins the game? Answer Question - (2nd round) Andy and Marjorie are playing tennis. The points system is as follows: there are two conditions for a player to win a game:

1) A player must reach four points in that game before their opponent. So for example, if Andy wins four out of the first five points, then he wins 4-1.

You may assume for now that once the set reaches 6-6, it ends in a tie (so no 'tiebreaker').

iii. The probabilities of winning each point are the same as before, 25% for Andy and 75% for Marjorie. But now the probability of Andy winning from deuce is 50% (Andy does well in pressure situations). Given that Marjorie is up 2-0 in a game, what is the probability that she goes on to win the game? Answer Question - (2nd round) Andy and Marjorie are playing tennis. The points system is as follows: there are two conditions for a player to win a game:

You may assume for now that once the set reaches 6-6, it ends in a tie (so no 'tiebreaker').

iv. Same probabilities as before. Now, if she gets to 6-6, Andy and Marjorie will play a tiebreaker. You may assume that each has a 50% of winning the tiebreaker and consequently winning the set (Andy plays significantly better under pressure). They play a best of three sets match, i.e. the first person to win two sets wins the match. Which is more likely to occur: the match finishing in 2 sets or the match finishing in 3 sets? [This question is a bit weird in my personal opinion] Answer Question - (3rd round) Describe a time when you achieved something greater than your peers. [There are in total 3-4 questions like this. They call them 'competency-based questions'.] Answer Question
- (3rd round) There is a mental math question at the end, pay attention. Usually they like multiplication with numbers that both have two digits. They only give you 5 seconds to prepare, but notice that you have 3 extra seconds at the end of these 5 seconds (the extra time is to give you time to set properly in front of the camera), so in total you have 8 seconds, and this time should be sufficient for you. Answer Question
- (4th round) Interview 1:

10 min competency-based questions (e.g. tell me something I cannot see on your CV, etc.).

10 min market making game. No pen and paper allowed. You have to make a market on the value of a pen. You are only allowed integers. The spread must always be 6 and you know that the last traded pen was traded at 10. Thus, the first market you make is 7-13. The interviewer buys 13. Then he says that the value of the pen becomes the value of the last trade, hence the second market is 10-16. The interviewer buys 16. The third market is 13-19. The interviewer buy 19. The fourth market is 16-22. The interviewer buys 22 and stops the game. He tells you that the value of the pen is now 22. What is your position? Your position is -4. What is your PnL? Your PnL is [(-9) + (-6) + (-3) + (0)] = -18. What trades do you have to make to make the minimum profit? You made 4 sells at an average of (13+16+19+22)/4 = 17.5, therefore you now need to buy 4 times the pen at 17 in order to make the minimum profit. Then he asks: what would your profit be in this case? 0.5*4 = 2. [If you want to exercise on this, www.tradinginterview.com has a nice simulator. Notice that this game is very very fast so you need to stay focused]

10 min of logic questions / brainteasers. These are pretty standards:

i) how many rectangles, including squares, can be formed on a 8x8 chessboard? Answer is (9C2)^2 = 1296

ii) you have 8 balls, one of which weighs more than the others. Minimum number of measurements on a scale to recognize the odd-one-out? Solution is 2

iii) What if instead you have 12 balls but you do not know whether the dissimilar one is heavier or lighter? Solution is 4 [Read Heard on the Street if you want the explanation]

iv) The pirates question that you can find on Google, whose solution is 98, 0, 1, 0, 1.

v) Expected number of steps needed to reach the opposite corner of a cube. Solution: using Markov chains you get a system of 3 eqs in 3 unknowns and you find 10 steps on average.

vi) Divide a fraction like 17/7, and provide ten decimals. All in your mind. You either are good at it or you are not.

vii) Time for ants to leave a 1 meter long stick if they travel at 1 cm/sec. Solution is 100. [Read Heard on the Street for explanation].

viii) In a room there are n people. They write down their name on a sticker. All the stickers are put in a hat. Everyone draws one sticker. If one picks his name, he forms a new group. A new group is formed every time a loop is closed (e.g. A picks B, B picks C and C picks A, that's one group). Solution: general formula is En = sum of 1/k, for k=1 to k=n. A very similar one can be found on the famous Mark Joshi's book, so read it.

ix) Expected value of a die roll (3.5). Expected value of a die roll with option to re-roll (4.25). Expected value of a die roll with option to re-roll infinite amount of money paying 1£ per re-roll (https://math.stackexchange.com/questions/2078312/roll-a-dice-infinite-times-but-pay-1-to-play-strategy) Answer Question - (4th round) Interview 2 (with CEO): 15 min competency-based questions (very relaxed). 15 min a couple of brainteasers included above. Answer Question
- (5th round) This is going to be very very tough. You compete against 5 other candidates. The entire assessment lasts 4+ hours. As I said above there are many interviews on that day, but the only thing they care about is the market making game, so I won't spend too much time on the rest.

Market Making Game: 2 group trading games. 3 different games in total. You are given the following 20 numbers for all the 3 games: [1,2,3,4,5,26,27,28,29,30,36,37,38,39,40,66,67,68,69,70]. You have to make a market and trade different things depending on the game. In the first game you need to make a market on 6 numbers randomly drawn from that set (no repetitions). Everyone makes markets and trades on the sum of those 6 numbers. When all are happy, one number is revealed. Same process as before. Then the second number is revealed and so on until all numbers are revealed. In the second game, everyone is privately given a number from that set. You know only your number, but not other people's numbers. Moreover, there are two numbers on the table, picked from that set. These two numbers are unknown for the moment. This time you trade the sum of all numbers (6 private + 2 public ones). Again you make markets and trade. Again numbers on the table are revealed one by one. In the third game, everyone is privately given a number and you trade the sum of these 6 numbers given privately. Private numbers are revealed one by one without saying which number belongs to who. For all the games you need to be super-fast at updating your expected value and make reasonable markets and trades. You should keep your position as neutral as possible. The goal is to make profit at the end, but most importantly to make sensible markets. At the end you are required to give your position and amount of trades, as well as to compute your PnL. You need to practise this with friends if you wanna be good at it. Notice that they tend to put in the game extreme numbers (e.g. 1, 2, 3, 68, 69, 70) so that there is a lot of volatility in the market.

HR interview: expected salary (be cocky!) + do you have any other offers? + Motivation for trading? + Why Maven?

Trading interviews: brainteasers as reported in my previous question. Moreover one easy question with options: oil trades at 50£ today and tomorrow you are 100% sure it will trade at 100£; I give you 1 million £, what do you do with them? Solution: I buy today and sell tomorrow making a profit of 1 million £. Can you make more money than this with options? Yes, in addition to buying oil you can also sell put option contracts to those people who believe that the price of oil will drop tomorrow. Obviously if tomorrow the price increases to 100£ the other person is not going to use the option to sell at 50£. This way you will earn the cost of the option you issued!

Competency based questions that traders ask: Describe a time you had a conflict in a group. Describe when you things did not go as you expected. Can you explain to me in 2 minutes what you do in life/job? They do not really care

Presentation task: 10 min to prepare a topic picked from a list of 7-8. You won't be able to use internet: they want to see your hands during preparation. Some of the topics are: i) difference between prop trading firm and hedge fund. ii) analyse UK fiscal response to tackle economic impacts of COVID-19 pandemic. iii) What causes social inequality in the world and how can this be reduced? You present verbally for 5 min and get Q&A session for other 5 min. Answer Question
