In my specific case, the longest job I worked was for 4 years with a company that went out of business.

I became friends with the manager and was pretty close to his right hand man during the course of the businesses operation, but the time that I work for him was split up so I asked him if it was okay if he got a call for a job check to say that I had worked for him for that entire time period and he agreed, so that covered seven years of job hoppery as all one cohesive thing.

After I got my first big boy post college job they never really checked past the time I spent working there so it was just enough to get me through the door so I'd have a chance to prove myself and once I had proved myself I was clear.
