The standard pipeline is recruiter screen (15-20 min, non-technical, salary + why-C1) → CodeSignal OA → Power Day → Team Match. Some senior IC and manager loops insert a 30-45 minute hiring-manager phone chat between recruiter and OA; for MLE / Applied Research, an extra Tech Screen with one or two engineers sometimes precedes Power Day.

Power Day is the entire onsite. Four rounds run back to back the same day with short breaks between them, totalling roughly four and a half hours. Recruiters typically schedule it 1-3 weeks after the OA passes. Candidates can request a prep call with the recruiter beforehand — this is offered as a standard option, not a favor, and it walks through what each round will look like.

After Power Day, candidates who pass enter Team Match. A successful loop becomes a generic offer that is only finalized once a team commits. Team-match cycles run weeks long and can stall, especially in the slower Richmond, McLean, and Plano hubs. Candidates report being asked to interview again with hiring managers during team match even after Power Day approval; this is informal vetting, not a re-evaluation.

Intern and TDP (Technical Development Program, new-grad) pipelines compress the loop into a single Super Day with three 60-minute rounds (code-reading, simple coding, behavioral) and skip the case study; their bar is noticeably lower than full-time SDE.

Capital One's engineering loop is unusually predictable: a long CodeSignal OA gates everyone, then a single Power Day stitches four 45-60 minute rounds — coding, system design, case study, and behavioral — back to back. The technical bar is moderate but the case study and BQ rounds carry real weight, especially for MLE / Applied Research / Data Science where the business-context framing of a model decision is the differentiating signal.
