My interview journey after the initial screens leaned heavily into probability and statistics. Once I was past the earlier steps, I hit a technical screen that felt quite hard—more like the kinds of “quant researcher” probability/statistics drills people associate with textbooks or problem sets. The problems weren’t ju
The process started with an online assessment that, from what I was told, only a small fraction of applicants passed. Once I got through, a recruiter call set a positive tone and felt encouraging. The technical screen right after was the one that threw me off. The interviewer opened by introducing herself and asking m
After a recruiter outreach, I moved into a pretty straightforward early loop. I was asked to talk through my previous work and what I’d do in certain scenario-based situations. The technical part felt more “test” than “research chat”: I had a live coding-style prompt that was fairly easy compared with the later materia
I ended up going through a high-friction, multi-round process that felt like it was testing breadth as much as depth. It stretched to five rounds, and the overall journey covered a wide mix of topics: probability, puzzle-style questions, and also computer architecture and systems themes like networks and operating syst
I went through an assessment-heavy path where the later rounds clearly shifted from coding toward probability depth. After passing the earlier online steps, I hit a technical screen that focused on probability and statistics and felt genuinely hard—hard enough that it reminded me of the tougher Greenbook-style question
