I received an interview offer after submitting my resume during an on-campus visit. They promptly contacted me within a few days, expressing their interest.

I then had an on-campus interview with a Software Development Engineer. It was a 30-minute interview where I was asked one programming question. I had to write the code on the board.

The problem wasn't too difficult, and the interviewer continued to probe my thought process while I wrote the code, asking questions like, "Why did you choose this method? How would you test this? Is this the most efficient approach?"

I ended up arriving at a pretty good solution and felt confident I had performed well. However, I was not offered an on-site interview.

Thinking back on what I would do differently, I would ask more clarifying questions and more clearly explain why my solution is optimal. I sometimes get nervous, which causes me to not explain terms as clearly as I could. Nevertheless, it was a valuable experience and good interview practice.

Write code that would shuffle a deck of cards.

Explain why your solution is optimal and how you would test it.
