I applied through the campus career fair and was called in for a campus interview the next morning. The email explained that the interview would cover the application of algorithms and computer science fundamentals. It was a purely technical interview, which required coding on CoderPad.

The first question was intermediate level, but I complicated it by overthinking. After the interview, it struck me that it didn't actually require any computer science concepts to solve. The second question was easier, but again I started thinking about complicated computer science. The interviewer patiently listened to my solutions and asked questions.

In the end, he gave me time to ask questions about DoorDash, which he answered in detail. During the first part of the interview, however, he didn't seem much interested in talking about my background. He asked me to talk about it but seemed distracted. I guess they wanted to focus solely on technical skills.
