Circle K Software Engineer interview questions

The interview lasted about 20 minutes and was a mix of informal chat and technical questions. He asked some solid intermediate-level questions about databases and coding. one was about how to optimize a slow SQL query, and another was related to normalization and table relationships.

Interview was good and easy, took a lot of time but was worth it in the end. Staff was friendly and HR interviewed was followed by it. Took nearly 1 week to get the call after that.
