FIRST ROUND · 45 MINUTES
Quant Developer
Twenty questions on the code, the data structures and the machine underneath.
20 questions in 45 minutes. The clock does not stop.
No hints, no worked examples, no indication of difficulty.
You are never told whether an answer was right — not after a question, not at the halfway mark.
A good answer sometimes draws a follow-up, exactly as it would in the room.
You may leave a question blank and move on. Blank scores the same as wrong, and costs less time.
Nothing here asks you to write code. It asks the questions an interviewer asks about the code you wrote.
Everything — scores, mistakes, the correct answers, and what to study — arrives in the debrief.
Once you press this the clock runs for 45 minutes without stopping.
