Yeah, it's like every school district: there is an amazing amount of politics going on where it's entirely unnecessary. Whites grumble about the "Hispanic mafia," where Latinos get into jobs. African-Americans are complained at similarly. (Of course, there are overwhelming numbers of whites at the district, so who's to know?) This silliness is just one example of what goes on there.
HR has no competence at actually finding and hiring qualified people. That's not so much a zinger at HR as much as it's a failure of the district to have even-handed ways of hiring for quality across the district. Principals basically can hire whom they want, and so long as they technically meet HR's guidelines, they're in. Of course, if you don't meet even a tweaky, technical guideline (like number of years of education, even for a non-teaching job), then you'll have to wait until you have the right service years , or get that dang degree, to get the job which you're qualified for.
Many of the top administrators are woefully incompetent at their jobs, and jobs are created just to keep incompetents in place. This runs the spectrum, from administrators "downtown" to long-term and highly-paid people at campuses. While this in of itself isn't a downside to working at the District, you'll probably bump up against these people when you work here, and that's sure to be a frustrating experience: their only priority is to keep their position unchallenged and unremarked, no matter who else is hurt by that -- including students.
On the technology side, administrative incompetence is practically the name of the game. If you're looking for a management position here, be warned: it's a hard job to do well without getting frustrated. I've seen a revolving door of managers through that department, with a lot of unhappy people stuck in place.
