Columbia University Postdoctoral Research Scientist interview questions

I was called by my professor and it was one to one interview. I just had to present my previous dissertation work. It was very simple as it was for postdoctoral position. I was just asked questions based on my presentation and topic.

emailed the PI, wrote back after 1 week. 2 weeks later on-site interview and offer same day. gave a 1 hour presentation in front of the lab. overall very nice experience
