Worked at Cisco for 17+ years, got LR'ed, no problem I thought, I'll find something. See I figured that if someone asked me why I stayed so long, I'd explain about how I changed roles every 3-5 years, changed jobs, big company so can move around, not institutionalized, etc...
What I never realized until I was "out" looking for jobs was just how much the average recruiter/hiring manager/ HR person had an almost personal issue with me and a preconceived notion of what a Cisco-long-timer was like.
Almost like sometime maybe around 2008 the market changed w/o me ever knowing it, and every year at Cisco was like a "negative" mark against me.
Anyway, I landed another job eventually, but it was admittedly harder than I had ever thought and harder than I had prepared for. Had nothing (I think nothing) to do with my age at the time, probably not even the jobs I applied for (wasn't picky, applied to almost any kind of salesy-vendorish job, IC,manager,team-mule, whatever, and must've been 100+).
Good luck everyone, and be sure to have at least 6 months expenses in cash and then CUT-BACK expenses to the bone. You never know...
