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.

The Power Day was the part that stood out most, largely because the questions felt very standardized. After applying through the portal, a recruiter contacted me and asked me to complete a CodeSignal assessment. It had four questions: two easy array problems, a medium string-manipulation question, and a hard dynamic-programming problem similar to LIS. I then had a recruiter screen and a hiring-manager conversation focused on my past experience, tech stack, and behavioral questions.
The final virtual Power Day consisted of four back-to-back meetings covering system design, a case study, behavioral questions, and a technical round. The process was smooth and the interviewers were friendly; the recruiter also did a good job explaining what to expect. On the technical side, I saw a graph problem and a couple of basic LeetCode-style questions. There was also an airplane-themed question, plus a code test involving a script. The case portion was a distinct round rather than being folded into the technical discussion.
I did not receive an offer. My main takeaway is to treat the assessment seriously, especially the DP question, and spend time researching recurring Capital One Power Day prompts. Be ready to switch quickly between system design, a case discussion, behavioral examples, and straightforward coding in one continuous final loop.
Prep tip from this candidate
Practice a four-question CodeSignal format that includes easy arrays, medium string manipulation, and a hard LIS-style DP problem. Also research recurring Power Day prompts, including the airplane question and the separate case-study round.

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.
