Interview Process

The interview process began with an Online Assessment (OA) that required the use of a camera. It consisted of four questions (LeetCode style), with a passing score of around 400 out of 600. Approximately two weeks later, I received an invitation for the Super Day. The Super Day included one behavioral round where I was asked why I studied computer science, why I wanted to join Capital One, and how I collaborate within a team. There was also a case round that included some coding, primarily focused on understanding and explaining code. Additionally, there was a technical round that leaned towards system design rather than typical LeetCode questions. My specific question was to design a transaction class to handle withdrawals and deposits.

Tips & Insights

Be prepared to discuss your motivations for studying computer science and your teamwork experiences. Focus on understanding code thoroughly, as the coding portion may not be purely algorithmic. For system design, think about practical applications and how to structure your code effectively.
