The thing is, they need you to be available on short notice for long hours usually during the week. If you have a consistent day job then basically forget it. They'll give you an online account that is essentially a calender. It'll be your job to update each day with either a green or red square meaning available or not available respectively. I finally got a salaried job in my trained field last week so I won't be an extra any longer. It's interesting though because you never know where it will go. I was only getting $10 an hour so it kinda sucked. A friend of mine in the city had better luck. On her 'things you can do' portion of the questionnaire, she put 'kayaking'. They called her and her husband in to do a car commercial which in turn aired during the last Superbowl and they made roughly $25,000 for literally 1 second of airtime! She showed me the commercial and was like 'There! Did you see me? That was my foot!' Ha! And she was paid each time it aired. Crazy business...
