Question 1
Rearranging blocks in a matrix was one question I remember.
I applied online. The process took 2 weeks. I interviewed at Capital One in Aug 2025
Interview
Started with initial code assessment, looks like autogenerated by the system. I was able to get 2 correct, 1 attempted and 1 too hard to attempt(4 in total). Followed by a call with recruiter to setup next round of interviews. Totally there were five interviews. In-person coding interview, 2 behavioral, 1 technical case interview and 1 Design and Architecture. All interviews are an hour each with 10 mins at the end to ask questions to the interviewer. During behavioral, interviewer would take notes all the time to capture your response.
Overall experience was neutral. As I felt it all depends on the interviewer taking the interview from other end with his background and skills to match yours. Recently, technical landscape has widened. If you are skilled in application development and if you are getting an interviewer with infrastructure background then naturally you will not be able to impress with the details you give. Expect few minutes delay in them(interviewer) joining the call.

Question 1
1. Typical code signal assessment with 4 questions. First 2 easy, 3rd question was hard and 4th was of medium complexity.
2. In person code interview with medium complexity. Make use of library functions if possible.
3. Behavioral (Using STAR methodology) - Share details on the challenge you faced with your team and how did you solve that. Tell me a time how you convinced a stake holder to agree on your approach. Tell me a time how you handled conflict with a team member.
4. Case interview - Improving efficiency of a banking chatbot and tracing the code on results and suggesting possible improvements. Less math and more technical.
5. Technical design and architecture - Design and architect a banking system.
Interview process was not bad. 3 total interviews including recruiter call. I did two zoom interviews with the hiring manager and another manager from a different Cafe. It was a little unorganized.
