Simply Hired Junior Software Engineer interview questions

I first had two phone screens with their senior QA manager and CTO. They ask you to explain technical terms. After that, I had an onsite interview. I met their Technical Lead, QA manager, CTO, and President. Only the technical lead guy ask coding questions/puzzles/database questions. Both the QA manager and CTO have spoken on the phone with me. The manager lady asks many behavioral questions. The CTO asks about the same set of questions (HTTP, how do browsers work,...etc) as during phone screens. The President asks more behavioral questions to understand your characteristics. After the onsite, they haven't get back to me until 4 weeks later. They ask for another onsite interview. I met their QA manager, CTO again and CEO at this time. Their CEO is a really elegant leader. I enjoy talking with him very much. I got an offer the day after but instead of full-time position, they make it a contract to hire one. I think they are very cautious about hiring people.
