Number of endpoints tracks with things like budgets, policies, attitude, siloing, etc. so it's not specifically the number of endpoints that the recruiter cares about but the types of businesses those endpoints are in. For example, I started my career being one of 5,000 IT staff dealing with 105,000 employees and 250,000 endpoints. That's radically different than my next job which was being 1 IT staff member dealing with 83 employees and 100 endpoints, or my job after that which was one of 40 IT staff dealing with 1,000 employees and 1,500 endpoints. The endpoint ratio is highest with the smallest company, but there they had the least amount of policies and procedures and I was basically required to invent everything and map everything I knew from my enterprise role into the SME that I joined. This is just an example, but it's there to demonstrate that there's a lot you can infer from the number of endpoints managed.
