Multiple interview rounds, varying with the role, will be conducted during your day at the Kroger office. Your technical prowess, including programming and system design capabilities, will be evaluated against the finalized candidates throughout these interviews.

In addition to technical questions, you should prepare for behavioral and situational questions. Be ready to discuss past projects, challenges faced, and how you handled them. Depending on the team, expect a mix of whiteboard, pair programming, and in-depth discussions on your technical approach to problems.

Pre-Recorded Interview Questions
