Most software engineers do a phone screen first. I had two referrals who recommended me highly, so I skipped the phone screen and went straight to on-site interviews.

Five technical interviews in a single day, with a break for lunch.

Interviews were heavy on coding, algorithms, and software design. Practice solving coding problems on a whiteboard.

I don't remember it exactly, but a coding question in my first interview with an engineer who didn't speak English very well. I had no feedback from her about whether I was even on the right track. She just typed into her laptop and said almost nothing.
