J.P. Morgan interview questions

First round on-campus. Simple programming questions (Very simple for the CSE background), one question on data analysis related to Linear regression. He also asked me "How would you explain the Linear regression to the non- technical person?" Got the result after 3-4 weeks that I'm not invited for the next rounds.

I applied online and was offered an invitation to an event that I attended and had two interviews during. During the event we heard from upper level executives and toured the office.
