Fast Four interview questions

The first interview went well. I spoke with the CEO, who explained what the company does and, in a nutshell, what my job responsibilities will be. Salary range that was significantly lower than what I had anticipated and I made comment on it during interview. Because the job covered essentially three roles, the provided salary was insufficient in comparison to the responsibility and accountability. Nonetheless, after the first meeting, they invited me to the second round of interviews, which I accepted. Two people asked a lot of questions, which was fine, and they mentioned how my background was ideal for this position. Never heard back from them.
