Had an online coding assessment, which asked a LeetCode hard question. I was given an hour to finish it with no test cases given. It was barely enough time for me to finish the solution and test it.

Phone screen 1 was on linux fundamentals. I was asked to write a feature for a C++ library on the linux command line.

Phone screen 2 was on C++ implementation skills. I was asked to write a unordered_map class. My implementation had a bunch of issues and I ended up not passing PS2. There should be one final round of onsite interview to finish off the process.
Interview Questions
Implement an unordered_map class in C++

Submitted a resume at a career fair and also applied online. Received an initial Coding and Mathematics assessment. The assessment was challenging and mainly brainteasers with some Prob/Stats. The coding consisted of 2 questions/exercises, one was pretty challenging the other was easy. I passed the assessment and had 2 phone interviews 3 weeks after; one was the HR and other was with a trader. The questions in the phone call with the trader were pretty challenging and while I was able to get 2/4 correct. I did not make it to the next round.
Interview Questions
This one was an absolute doozy:
Four points are chosen uniformly at random on the surface of a sphere. What is the probability that the center of the sphere lies inside the tetrahedron whose vertices are at the four points?

There was also a Markov Chain chess question. It essentially went as follows:
You and I play chess. 1/2 games end in draws and in the other half I win with 2/3 probability and you win with 1/3. If the matches with either of us winning 3 consecutive games, what is the probability that I win?

Tough interview had several tough probability questions. I was able to solve most of them. There were 7 questions and they all had to do with probability distributions.
Interview Questions
1) What is the expected value of a random variable x in [0,10]? What is the variance?
2) What is the expected value of rolling a fair dice? What if you can re-roll? What if the re-roll cost 1 dollar and you make 1 dollar for every dot on the die that is shown?
3) What is the ratio of the total number of days in a year to the days in a month for an average year?
4) In how many ways can you have three numbers that sum to 10? What about 11?
5) In how many ways can you have three numbers that some to n for any n greater than or equal to 3?

Interview Questions
There are 5 pirates and they are trying to split 100 gold coins in a rational way. The most senior pirate will choose to split in a certain way and all the other pirates will vote to agree or disagree. The most senior pirate is always the one to propose the split and must get at least a majority of the votes from the other pirates for the split to work. How should the senior-most pirate split the 100 gold coins such that he will survive and maximize his own earnings? The pirates are all rational, so will all try to maximize their own earnings. If the pirates can't agree, they will overthrow the oldest pirate and make their own split.

The first few rounds are phone interviews with increasingly difficult brain teasers and probability questions. Make sure you study the quant interview books out there as many questions can come from those. The final round is tough in the sense that they really want to see how you think and might throw in some Fermi questions/general reasoning stuff rather than out of the book brain teasers.
Interview Questions
What's the probability of drawing a full house out of a standard shuffled 52 card deck? Assume no replacement.
I roll a die three times. What's the probability that the resulting numbers are in strictly ascending order?

The first round interview was phone interview with a trader. He asked me a few different probability questions (dice etc.) and a couple of brain teaser/math type questions. The second round was with a slightly higher up trader and featured some more background/fit questions along with some harder puzzle questions. I'm told the last round of the process would have been with the founder of the firm.
Interview Questions

Each mouse can test as many bottles of wine as you choose, but the results of the test all emerge simultaneously. Describe a strategy to maximize the number of bottles saved.
