Temp-to-hire openings around Phoenix - any advice?

I am looking at seasonal jobs around Phoenix that might lead to something longer. I have read a lot of threads here and could not find my exact situation. The pay is hourly with weekly deposits. Is it worth applying to several at once?

Keep a list of supervisors' names. A reference from one of them helped me land my next job.

Ask early about permanent openings. Some teams fill them from their seasonal list.
