Let's say we have a timer with precision to nano seconds (9 digits). For all the missing values we just put nine 0's. What is the probability of at least 1 missing value given that we see 15 data points with 0's in the end in 10^5 data.

First I had a behavioral phone screen interview then I was contacted for an in person technical interview a few days later.
Interview Questions
No difficult questions, just general questions about my resume, then general questions about C and pointers and arrays. Then I was asked about how I would store key value pairs. And then ended in a discussion about how I would implement a hash map data structure. I was asked about the tradeoffs between various implementations. I had to implement methods to add the key to the hashmap and method to retrieve a key from the hashmap. I was also asked general questions about what my previous experiences at internships were like and shared some information about working the company

Interview
I applied online. They came to my campus. I was interviewed by two people for 45 minutes. They asked math and coding questions. At the onsite, they gave a presentation on the quant research internship. I had two quant interviews each 45 minutes I think it was, plus one programming interview that was an hour. The times may be wrong.
Interview Questions
On campus, they asked how to play a game where you call the next card and get a dollar if it's red, at which point the game is done. If you don't call, the next card is discarded and the game continues with the remaining cards. There was a CS question about implementing an infinite stream and a math problem about the probability an array is sorted after swapping the first two if they're out of order, swapping the new second and third if they're out of order, and so on until swapping the last two if they're out of order.

Interview
I am contacted by a quantitative researcher in Chicago. He focused heavily on my PhD research and drilled in several details, asking "why would you do this instead of that" type of questions. Then he asked one question of probability which can be solved by Bayesian formula.
Interview Questions
Suppose you backtested a trading strategy, it did very well. But in live trading, you keep losing money, what would you do?
Suppose you sit on the road side and observe cars driving by. Assume the distribution of cars driving by is according to an exponential distribution. Now you observe a first car after sitting for x mins, a second car after sitting for y min. Given those observations, can you estimate the parameter in the distribution?
What machine learning methods have you used? Followed by several "why" and "what is the pros/cons" types of question. What are ensemble methods? Can you describe boosted tree methods?

Interview
On-campus recruiting process: initial interview was a whiteboard interview with two other engineers and if you passed that one, there was a full day of onsite interviews at its Chicago office
Interview Questions
The interview was 45 minutes long and consisted of a straightforward whiteboard question with two separate tasks:
1. Convert decimal-based number to a 16-bit binary representation
2. Represent as 4x4 matrix of 0s and 1s
3. Detect if path of 0s exists in matrix from top left to bottom right cell and if so, print out the path in the format of a string; otherwise, return a "No path" string

Interviewers were nice and gave hints as to how to solve the problem. They let you use any language you want.

Interview
The first interview was on-campus. They were very friendly and willing to help. Had 2 technical coding questions that lasted ~30 minutes. Passed to the final round, where they flew me to Chicago. There, it was a superday consisting of 4 interviews. One was a purely coding interview with a laptop in front of me (C++). Another was purely mathematical/linear algebra done on the whiteboard. The third and fourth were pen/paper brainteaser and math/probability questions. Though I didn't get enough questions to receive an offer, they were very helpful and nice. There isn't really a way to game their system besides just knowing how to solve data structures, algorithms, and probability questions.
Interview Questions
Implement a trie in C++.
Swap two variables without additional storage (i.e. no using a temp).
How many 0's are in 1000! (factorial)?

It was a simply an email screen. I contacted the recruiter multiple times, but didn't get a response until a while. They told me they were looking for a person with more of a CS background. I submitted my resume via a contact at Stanford. The company seemed full of smart programmers. I got the impression that base was really high there.
