Imprint energy interview questions

I met with two people. They were both very easy going and I felt very comfortable during the interview. They wanted to know about my experience working in a team. The interview was about 30min but they encourage for me to email questions if I had any after the interview. I was selected to pass the second round in which I had to provide a writing sample on something that I have worked on. Further, I passed the second round and was selected to for the third round in which I would have to prep a presentation. The presentation topic was left to my choice and it had to be 30min. I declined the third round given I had accepted another offer.
