Jane Street Software Engineer interview experience

I went through multiple morning rounds and they ran like progressing check-ins, where each part mattered for whether I would continue. I got far enough to complete two of the segments in the first round, and then I worked through the parts assigned across the next round as well.

The day ended a bit early for me—I was sent home after lunch. There was also a small detail that stood out: they’d allow you to take lunch in a special room if things didn’t go well, which made the environment feel both procedural and considerate.

I didn’t end up getting an offer, but it didn’t feel cruel or random.
