Pros: free lunches, health and life insurance, careerwear, fast-paced environment when busy
Cons: lots of slow periods, pay isn't really all that great.
PSAV is okay when it comes to being a job straight out of college. If you're not new to A/V you'll learn all about it but it is not going to test those of you who are more experienced and looking for a challenge. The work is very physical, there will be lots of heavy lifting, sometimes in a suit. You'll also get good benefits for a first time gig however the pay is painfully low. Every tech gets $13/hour starting out and you aren't eligible for raises or promotions until you have a year under your belt. You'll also find for most properties that you'll only know your schedule about a week in advance making it difficult to schedule social gatherings. I've also found most hotel staff do not appreciate A/V people but you can usually work around it or grit your teeth for the sake of getting your job done. Finally there's a lot of slow points where there will be no work for you to do and you'll find yourself with more days off than days you're working and unless you're a director or one of the other salaried positions, that means you don't get paid.
PSAV is better than working retail, but not by much. If you have a chance at a more professional gig definitely take it.
