Also, please reconsider your decision to feature Google and Facebook as prominently as "featured employers". If it's for security, maintenance, and janitorial work, it's more practical to list the agencies that they hire temps from. Otherwise, look no further than nearby East Palo Alto and one will find that neither company particularly cares about rehabilitating ex-offenders or people from at-risk communities for any type of technical employment.

The general rule with Silicon Valley and San Francisco companies is to take everything they say in public or through their carefully worded P.R. with a grain of salt, and actually find out first hand if they practice what they preach hiring outliers with respect to diversity, records/credit/etc, non-Ivy League degrees, etc.
