My interview was for a 6-month internship position as a UI Software Engineer. I only ever had one interview with the hiring manager and it was a very casual free-flowing conversation:
First they asked me to explain my background and resume
Then they asked me specific questions about Virtual Machines, coding languages, my experiences with them, etc.
Then they asked me about which projects I'm most proud of and which ones I struggled on and to describe how I worked through them.
All-in-all, very fair, concise, and intimate interview which only took about an hour. After that, I received the offer and accepted
