Ask HN: Is bait and switch jobs common in IT

Hi,

I started an application process for a Senior Software Engineering Manager position in SV. Its an approx 150 employee company lead by elite univ alumnus.

Everything went very well, phone screens, tech screens, behaviorals .... I actually enjoyed the interviewing process and like the company.

Then the job offer came and they made an offer for Engineering Manager Position (no Senior). That has left me completely confused.

Has this happened to other folks? Would this be an honest mistake on their part or are they just crooks? If it was non-senior position I would never have applied. It was very anti-climactic for me :-(

What do you think?
