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.

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.

First, some questions about basic C++ knowledge. Then came a medium coding problem. However, the interviewer left while I was coding. He asked me to finish it before he came back. I waited for 5 more minutes for him after I finished the code.
