Jump Trading Intern interview questions

I had to submit an online application. I submitted my resume and then was given a first round interview. Questions were very difficult and centered around probability and quick-fire. I was rejected quickly after this round.

First step was an HR interview (15-30 minutes) followed by a techical interview and a final round. All rounds are quite competitive. The last round is held in person, while the two other aee conducted through Zoom.
