J.P. Morgan Software Developer Internship interview questions

I received an email with the online coding assessment, it was two problems one was easy with 20 min to solve and the other is hard with 40 min to solve, after solving each you will record 3 min video explain how you solved it and if there are more time what would you do to make answer better.

The online test was held and they asked easy questions and did random shortlisting. Despite doing both problems, many were not selected for next rounds. They only took circuital students.
