Capital One interview questions

The Capital One interview process started with an online take-home assessment, which included four coding problems on LeetCode. The difficulty levels were two easy questions, one medium, and one hard. This round tested my ability to write clean, efficient code and handle algorithmic challenges under time constraints. After successfully completing the assessment, I was invited to the Power Day, which consisted of four back-to-back interview rounds. The first was a technical interview focused on coding and problem-solving skills. The second round covered system design, where I was asked to design scalable, reliable systems and explain my architectural choices. The third was a case interview that assessed my analytical thinking and how I approach real-world business problems using a structured, data-driven mindset. Finally, the process concluded with a behavioral interview, which focused on my teamwork, leadership, and communication skills, as well as how I align with Capital One’s values and culture.

First round was excel based problem solving that was recorded and relatively challenging Second round was two business cases and product case, two business cases were quite quantitative and the product case was specific about a digital product.
