Do not even bother prepping for this interview. The CEO is usually at least 30 minutes late to your interview. He does not care about your qualifications or credentials. He would rather hire a freshman with 0 technical skills that's willing to work for $12-$15 an hour over a qualified candidate with a bachelors or masters degree in computer science for $25+ an hour. He says a raise is possible after 6 months of work, but if you demand for higher than $25/hr he'll shortly start looking for other candidates willing to work for $15/hr to replace you and then fire you within a few weeks.
