Perceptive, since that's exactly the reason I ask so many questions before I physically drive out to meet someone. On the other hand, refusing to answer questions is pretty much guaranteed to put my guard up, too, which is contrary to their goals.
I'm an ITT graduate. I experienced none of what was in the article. That may have been their tactics at some point, but it wasn't used on me in the early 00's. Perhaps the person who was talking to me knew their job really well and knew it wasn't a good idea.
In the end, I learned nearly nothing (I was self-taught already and mostly wanted the paperwork) and got a 4.0 GPA. I watched others around me struggle with basic programming. Most of them quit, and I graduated with about 4 others in that program.
They claimed that a high percentage of their graduates had jobs when they graduated, but what they didn't make clear was that those jobs weren't necessarily in their field. I didn't have a job at all, most others didn't have a job in IT, and the 1 who did got it on their own at their current employer, Disney. Despite them providing no leads, they blamed my lack of job on me and how I approached it. No attempt was made beyond basic resume and interview coaching. That guy ended up getting fired after my father made a huge stink about it repeatedly. (He wasn't the only one, I gathered.)
When I did get hired, it was by a company that cared more about my skill than anything, and I actually looked worse on paper than the other main candidate. The company paid for BrainBench exams and I blew the other guy away, which got me hired. The paperwork I cared so much about has never been useful. The original estimate was $30k. I paid $23k because I transferred in some credits and tested out of others.
