J.P. Morgan SWE Intern interview questions

In behavioral they ask you questions like how you lead a team/any challenges you've gone through, talking about projects you've done etc. Standard behavioral stuff. In the technical: one to two leetcode easy probs, have to describe your solution/space/time complexity. Additionally, might ask you some general object oriented programming questions like what is abstraction, polymorphism (give examples etc). Also will ask some general database terminology questions (can say you are not sure if you don't know).

Please talk about a time that you worked in a group project.
