Maybe changing your own view a bit gets you closer to reality.
This! I'm reading in the thread here about people not arranging the right times, and people responding to recruiters who clearly don't care, and people jumping through all kinds of hoops, and I'm just here kind of in disbelief.
A good way to think about interviewing/being recruited, is in terms of dating. If an attractive woman says she's gonna call you, never does, then when you see her on the street she gives you some "Oh my dad's aunt's cousin's dog was sick" excuse, you're pretty much an idiot for ever thinking she was into you in the first place, and continuing to want her.
Another thing is that these folks have no idea that by continuing to be straddled and dragged along (and basically bullshitted), they're confirming that "Hey, I'm desperate for this job, so sure, I'll let you walk all over me". Which thus reduces their attractiveness as candidates. A recruiter misses a call with me? No reply. A company doesn't follow through on what they said they'd do or bullshits me in the slightest way? No reply. This approach is definitely a gamble, but you have to have confidence in the fact that "Hey, I'm great at what I do and anyone who gets me is lucky to have me".
Again, not that different from dating.
But some people actually are desperate, especially if they need to put a foot in the door with the big players of industry. We all desire basic decency and not being treated as nuisance.
