If it's any consolation I got headhunted by PlanGrid earlier this year. I knew of them in a professional context and was ready to sign on the dotted line after the recruiter's opening salvo. Turns out the hiring manager and recruiter were completely disorganized and seemed more interested in playing games than actually hiring. PlanGrid basically snatched defeat from the jaws of victory.
Reading this news blurb resulted in a bit of mixed emotions for me. Earlier this year, prior to my run-in with PlanGrid, I walked away from a decent chunk of unvested stock options in a rather well known publicly traded company. I suppose they deserve each other.
