My husband has spent his career in tech as a product evangelist--lots of energetic presentations to app developers (plus many other roles)--and had been with his last company for 18 years before being laid off due to reorganization. He's really been striking out on the tech job front these last two years. Is it ageism? What resources can he turn to? If tech is no good, what other niche should he consider vis-a-vis evangelical skills?
