I would have to agree with Butch here. It takes a while to learn the ropes and being a sweeper is top-tier. In theory, the sweep technician should be the last person through a system and should know every single thing from HE to EOL.
If you try to pass yourself off as a sweeper, and are not, you will get run off a job quicker than you could imagine. Worst of all, sweep deals directly with system managers and techs on a daily basis - if you screw it up - you get black balled at a HIGH level... you will be wondering for years why you will keep getting turned down for work...
Work the ladder up - you will know more, be a better tech, and get more respect (RIP Rodney) in the long run.
