Gaming Capital Group interview questions

Was a okay process. I sat in front of 3 people and they all 3 asked me questions. The gave me a tour of where I would work. They introduced me to other people who worked there. I went home after the interview and they said they would call me. They contacted me a couple of days later and offered me a job and offered me a salary. I was not that familiar with negotiating my salary. I thought what they offered was fair so I took it. I would have, had I known how to negotiate, haggle a severance package. The HR lady that hired me quit to find a job closer to home. And I felt that the company lost a valuable asset.
