La procedura ha richiesto più di una settimana. Ho sostenuto un colloquio presso Two Sigma
Colloquio
Phone screen. Hacker rank coding test ( graph search and dynamic programming) and a phone interview with technical questions.
Overall I got the impression that they are more concerned with pop quizzing you rather than your experience/accomplishments. Black and Sholes probably wouldn't have gotten a job here because they didn't know how to construct a median heap on the fly off the top of their head.

Colloquio
It will be a phone interview first. They will ask you technical questions about probability/ statistics. The interviewer is friendly, but the question is not easy. The process is good.
Domande di colloquio [1]
Domanda 1
There are 11 people, they want to make sure that every 6 of them can open a box. How many keys at least for each person should have? How many locks? (One key can only open one lock, but one lock can be opened by many keys)

Virtual Onsite: coding + research + talk about a paper you read recently + statistics foundations
Very likely failed in statistics foundations.
Need more serious preparations to get through the position.

Ho presentato la mia candidatura online. La procedura ha richiesto una settimana. Ho sostenuto un colloquio presso Two Sigma (New York, NY) nel mese di nov 2023
Colloquio
Two rounds of probability theory followed by two rounds of coding. The probability theory round were consists of some puzzles, counting and Markov chains. They focused on random walks induced by certain real-life questions.

Domanda 1
I do not remember the exact questions but it was heavily focused on Markov chains.
