I&#x27;ll use myself as an example -- I work as a programmer in the Defense industry.  I&#x27;ve wanted out for years.  So every so often I start sending out resumes and going on interviews.<p>After wasting about half of my vacation time on (multiple) rounds of interviews with each prospective employer (that ultimately lead nowhere -- most often, a potential employer who inexplicably stops communicating with me), I give up.<p>Then, when I <i>need</i> to find a new job (project&#x2F;contract ending, etc.), I do the safe thing and apply to other defense companies, because getting an interview almost always results in an offer (and no multiple-rounds of white-board hazing either).  After a while at the new job I&#x27;ll start looking outside the industry again --- and promptly get pounded back into my pigeonhole :)
