Landed a new job at a Fortune 200 company, probably easiest interview process ever had: an outreach by a recruiter, a ten minute call with the hiring manager, a two-hour total interview with the hiring manager, two would-be colleagues and the CFO, respectively. In the interviews with the other three I picked up that this role was dreamed up by the hiring manager, faced skepticism within the exec ranks, and he had to use a lot of political capital to get it approved.
Anyway, get hired and am excited but feeling the pressure. First day on the job I learn the company's annual all-day meeting with vendor partners will be held in two days at a hotel in San Diego. As I will need to work with these folks I pushed my new boss to let me attend. He was dubious, given I had just started but agreed.
Go to the event, top notch event all around, 300 or so reps of vendors in attendance, introduced myself to a lot of folks. Late in the day, my new boss comes over and says, "Bob, I'd like to introduce you to ** ******" (with no augmenting info of who he was). I smile, shake his hand and ask what his role is with the company. "Uh, I'm the President", he said with notable annoyance. Out of the corner of my eye I see my boss's face drop. This was his direct boss. I don't recall how I responded, but the conversation ended quickly after that. Fortunately, the guy (who I later came to know had a healthy ego) never held it against me.
