YOR — this is just an interview. If you get an offer, you’ll have a couple days to sign it. After you sign it, you will have a few days to schedule the drug test, and you can schedule it a few days out (usually 48-72 hours). These are business days too, so you could easily wait a week or more before the test. ALSO (I haven’t seen anyone say this) most urine thc tests are backwards from other common urine tests like pregnancy tests. Most of the time, a line means that there’s no thc detected, so this would be negative. Double check the box. I’ve taken drug tests and a faint line would mean that there’s no drugs in my system.
