Blood Drug Testing

What kind of drug test method are most jobs using these days?

I've got an interview coming up for a job (auto assembly plant) and I was wondering what kind of drug test they may do? Hair, urine, blood, saliva? What are most companies doing these days?

1. urine.
2. They will probably be forced to comply with the DOT. Therefore, they will use a urine test.
3. The most common test is drug urine test cup and if the result is positive they will send this to laboratory for confirmation
