Red Rock Events interview questions

Applied for the job off a job board, got a call soon after saying "My hiring manager noticed your resume, we do event-based marketing, great entry-level position, etc." Arrived for the interview to find five other people in the waiting room (that only sits four) waiting for their interviews. I waited 30 minutes to have a five minute interview, in which the "hiring manager" (who also happens to be the president of the company) promised potential of $75K+ salaries. The ACTUAL position they have you doing is managing roadshows in grocery stores, barely making $500 a week. I cancelled my second interview. This does not seem like a legitimate company.

Was scheduled for a 30 minute "get to know you" interview; interview started 40 minutes late and was cut short as the interviewer had a conference call that she needed to take. Was told the interview pool would be cut to 5 for a "hands on" interview requiring you to basically volunteer to work for free for an event and that all candidates would be notified by 5 pm that day. Never heard back either way. I believe all employers should have the courtesy of letting a candidate know they are not being considered for the next step
