Capital One Software Engineer candidates most often describe an initial online coding assessment before a Power Day-style interview day. The assessment format varies: several candidates saw four questions, while another described three timed levels. Reported examples include matrix traversal, graph/DFS, LRU cache implementation, prime counting, and string transformation. Practice clean, time-aware coding rather than relying on one problem pattern.
The interview day is broad rather than purely algorithmic. Candidates report technical discussions that use object-oriented exercises such as banking, card-game, and transaction systems. Be ready to clarify requirements, explain state and operations, and respond to follow-up questions about tradeoffs; candidates also report architecture conversations involving scalability, resiliency, distributed systems, and three-tier design.
Case discussions may combine business reasoning with code review, debugging, requirements, or quantitative analysis. Behavioral conversations commonly ask for concrete project examples, including challenging the status quo, feedback, or difficult work. Prepare concise STAR stories that make your role and outcome clear.
Reports differ on the exact Power Day schedule. Some candidates describe three interviews covering technical, behavioral, and case work, while others report four rounds with coding, design, case, and behavioral components. Treat the listed stages as reported possibilities rather than a guaranteed sequence, and use the recruiter’s preparation material if it is provided.

Synthesized from candidate reports. Individual experiences may vary.
Candidates commonly report an online assessment before later interviews. Formats vary from three timed levels to four questions, with accounts describing easier early questions and more demanding later work such as matrix traversal or graph/DFS.
Candidates report a compressed interview day that may include coding focused on building methods or modeling a system, rather than only a conventional algorithm prompt. Banking, payment, transaction, and other stateful examples recur across accounts.
Candidates report design conversations around banking, credit-card, payment, or file-system scenarios. Typically, the discussion may probe functional requirements, deeper tradeoffs, scalability, resiliency, or authorization rather than a single prescribed architecture.
Candidates describe case rounds that can involve business rules, debugging, code review, data or quantitative analysis, and discussion of pros and cons. The exact exercise varies, so practice structuring assumptions and checking requirements aloud.
Candidates report standard behavioral questions about projects, feedback, conflict, teamwork, and challenging the status quo. Prepare specific examples with a clear situation, actions you took, and measurable or observable results.
