Re: GPRS Project Coordinator
Is this a job with RIM? 
For starters, on the tech side, make sure you understand the differences between GPRS and WAP, and how GPRS has been a significant step towards 3G services.
Also it wouldn’t hurt to know the OSI/RM inside out!
Also read up on VoIP stuff, CDMA and TDMA protocols.
Make sure you use buzzwords like “always on” , “burst” packets etc.
Make sure you know what type of primary applications have generated GPRS traffic over the past few years… I suspect you’ll be asked about the application aspect of it, so better know the customers you’re catering for.

Good luck!
