Capital One's TDP (Technology Development Program) interview process involved a CodeSignal OA followed by a virtual Power Day. The Power Day was a ~4-hour marathon with three separate interviews and an hour break: a Technical (OOP, data structures, code modification), a Case Study (business scenario with code/logic), and a Behavioral (using the STAR method for teamwork/challenge questions).
