I'm at the same company for 10 year and my actual job description had evolved somewhat like this way: Cartographer > Database admin > Data scientist > Develloper > ... Because I felt like moving I talked to my boss and he agreed I start a part-time phd in the company. So chances are high that I'll stick around a few more years to achieve that. If after that a company is dumb enough to reject my CV based on a "to long in same company metric" that will be their problem, not mine... PS: In the long run I think we agree. The problem is that there is no absolute metric or Machine learning trickery to evaluate experience and value of an employee. Company that believe in or sell such metrics are the main problem IMHO.
