I applied online. The process took 3 months. I interviewed at J.P. Morgan (Glasgow, Scotland) in Dec 2018
Interview
Online form including CV. Then code test and hirevue questions. There were two code questions of average difficulty, similar to those on leetcode. Then you had to provide video explanations of your methods. Then there was another video questions with a separate technical question.
I firstly receive a code test but the platform is not very easy to use and I think the problems are too much for a pre-test. maybe they need to improve that.
