I am interested in applying at PRPD. I tried calling HR but they have yet to return my call. Can any please help me out with my questions?

What is starting pay?
Is promotions hard to get here?
Is there a step plan for pay, and how much is it per year ?
What kind of specialty units does this department have?
any continues off duty details and OT?
How is the call volume?
Do you have time for self initiatives (Running radar for Traffic)?

Thank you in advance for your answers.
