I applied online. The process took 5 weeks. I interviewed at Capital One (Birmingham, England) in Dec 2020
Interview
There was one coding test which was 3 questions long, 1st was easy, 2nd was medium, and the last one was medium difficulty as well. Then one-way interview where you had to record yourself answering questions with no retakes.
Power day (technical, behavioral, case study). Online assessment beforehand using code signal. Leetcode medium level questions for all (maybe 1 easy in the OA). Prepare for object oriented programming as well.
1 tech with easy leetcodes (4-5 subparts), 3 behavioral questions, and 1 case with information about understanding a C1 problem and applying the following provided information to create a solution.
