He first asked about project experience and behavioral questions. Then he asked about some technical problems. The interviewer was patient, and we had a really good talk. There was no long coding involved, possibly because it was just the first phone

Fairly routine. A standard "Tell us about you" section where you can talk about what you've done, followed by a standard technical algorithm question. I was given 45 minutes to complete the task.

Not too bad, and an average interview if you practice and understand the position. Practice for the interview, and make sure to research the position and be on top of up-to-date tech.
