J'ai postulé via un recruteur. Le processus a pris 3 semaines. J'ai passé un entretien chez DRW (Chicago, IL) en août 2017
Entretien
First, there was a phone screen where I was asked questions about CS fundamentals (data structures, mostly). Then I was asked to walk through a solution to an algorithm question over the phone.
Next, I had a take home test which took me approximately 10 hours to complete.
Finally, I had an onsite visit which was approximately 7 hours in total. I began following a coding prompt that took a little over an hour to complete. I was then interviewed by different parts of the company in 1 hour segments mostly about data structures and CS fundamentals. The interviewers had a pretty even balance of nice and aggressive personalities.

Leetcode like question with follow ups on c++ concepts like virtual memory, address space, etc. Coding everything from scratch and there’re also weird concepts like function pointer. Question was not too hard but need to remember concepts and syntax clearly

HR, take home coding tests, behavioral, technical discussion, live codings for several rounds.
The live codings are a bit hard. Some are about problems solving, some are about data structure and algorithms.

Entretien
Did a set of interviews in summer 25. The interviews were not that difficult, mostly problems you'll face in real life. The interviewers themselves were mostly nice, although a couple seemed like they didn't care, not very involved in the process.
Got rejected due to 2 sections having "mixed signals": one generic "not deep enough", the other didn't like the approach to solving a problem (it was solved on time anyway). Funnily enough, got praised for using the same approach in other section. Mixed signals also came from the people who wouldn't have been on the same team.
It would be nice if interviewers were aligned on evaluation criteria, otherwise it becomes a guessing game.
Other that that it was a positive experience and the rejection was delivered by phone, not a generic email.

Question 1
Some very down-to-earth problem on coding section, pleasantly surprised.
Unfamiliar algo problem, more like medium-hard.
And a data modelling exercise.
