Anyone had a "bait & switch"?
In essence: You applied for job X but
"Yeah that job has been filled, but maybe you're interested in Y?"
(X can be Haskell, CTO, .... and Y can be Php, architect, ....)
But this is not intentional bait, rather offering more opportunities for both sides and totally legit in my eyes. And it worked out well - at least for the company I work at...
I can see how that would be frustrating on your end, but I wouldn't immediately attribute it to malice.
You just can't steal people's time like that.
You've made a hiring decision, but you still have 2 strong candidates from the process that you know are good hires for other positions so why not ask what they feel about it?
