I will be honest, I don't know much about the UC Riverside program but I have worked with folks that have gone through similar "compressed" type situations and it can be challenge to get value out of them.
Unless the schools REALLY has great connections to employers for internships and/or a HUGE pipeline of graduates you probably will not get as much benefit as folks that have more contact with professors and on-campus recruiters.
Of course, depending on your situation, it may be OK to not as much access to these things. If, for instance, you already work for a municipality and they are desperate for somebody that understand GIS then maybe you could get a promotion after a program like this. Similarly, if you are part of large organization where you could transfer into a role that uses these skills that might work out really well.
The real "big money" side of GIS stuff is working for the "big guys" like Google or Apple or MapQuest or NavTech and you need to have a lot deeper technical skill set than the program lists --
Geographic Information Systems Certificate: Certificate Programs There are people with PhDs in Cartography and deep experience as hard core programmers that can make six figures...
On the other hand if you just want to "break in" to something different there are probably jobs at places from FedEx to the electric utilities that would pay decent money ($15/hr) for somebody that could help update the various systems that use internally to track changes in where their customers are and how that is reflected in GIS applications...
