Vantaggi
If you are over 50, take H1B pay and get a job. They are persistent in trying to get their former consultants more work. You can get medical insurance if you ask for it.
Svantaggi
The pay is low for any kind of engineer. Any benefits like medical insurance you pay the full price for out of your base pay. Consultants are not employees and hence are not invited to the customer (actual employer) Fourth of July party. This is not the fault of the company but rather of being a consultant. I was not allowed to telecommute by the customer due to the not trusted status of consultants which slowed down my work and forced extra 50 mile round-trips to the work site. I also got the impression that some vital technical information was being withheld presumably also due to the trust issue and that also impeded my work.
