I have been casually looking around for a new job for a few months now and had some Skype interviews so far. One of the companies I interviewed with flew me in for an on-site interview last week.
We had a series of interview rounds with short coffee breaks in between. When I was drinking coffee and chatting with the recruiter, I saw my current manager pass by in the hallway being escorted by one of the interviewers that had interviewed me just before. I am pretty sure he saw me as well, but we did not acknowledge each other.
I did relatively well in the interviews and they want to proceed with another round with a hiring manager, however I realized that I am probably not a good fit for their culture, so I plan on staying for a while longer at my current gig.
I am pretty sure that my boss was there for interviews as well as I do not see any other convincing reasons he would be there otherwise (the two companies are direct competitors in several key areas and the interview was in a different state).
I never told or otherwise indicated to my boss that I was looking around. My question is: should I bring it up with my boss next time we meet or just pretend it never happened.
