The only way to tell if someone can do the job is to look at their past accomplishments through a web of trust with other engineers, or by having them do the other job.

The whole country has at will employment and companies certainly aren't voluntarily signing any employment contract. Just fire someone if they turn out to be incompetent/fraud.
