I also would not recommend moving to California, absent a stable high paying job (six figures) or strong family ties. I escaped California after living there for a few decades (Irvine & Santa Barbara) and couldn't be happier.
The market is tough for recent graduates without work experience, from what I can tell, and there are certainly many jobs elsewhere across the nation. If you want to move for work and don't have strong ties to a particular area, you can have your pick of places. Between the high cost of living and inflated real estate prices, high taxes, drought issues, constant fires, mudslides, and earthquakes, California is probably not the best place to seek out if you have a choice. A million-dollar home in California can be a $200k home most other places in the country.
I try not to even travel to California on vacation any more. The last time I drove down I got stuck with a $30 fine for "toll evasion" due to not having a FasTrack pass or actual paper money on hand, with the Bay Area bridge toll bridge cartel. Every single north-south route through the Bay Area is tolled, cards are not accepted, and out of state license plates are no excuse.
