They call you ahead of time to schedule an interview. It's a phone interview, but there's a website where you have to complete five programming problems. I didn't do them all.

Phone interview after referral. No appointment was scheduled before the call, and the interview date could not be changed. This was very disadvantageous, as I had limited preparation time. The interview lasted 15 minutes.

I was asked some data structure questions and need you to explain the answers in detail. I was also asked one Spring Boot question about the `@Bean` annotation, and I need to explain that answer in detail.
