OPSWAT Intern Software Engineer interview questions

The onsite interview was with a few different people, from different teams, to evaluate my experience, skills, and interests. However I only received about 1-2 technical questions, and there was no whiteboard for answering the questions, I answered via talking. A week after I had a phone interview with one of the directors because this director wasn't able to interview me the day of the onsite. No technical questions during the phone interview, but I was required to go into details on my experience and skills.
