How long does weed stay in your system? if only hotboxed.?

I was at a party where there were about 15 people smokin it in a garage and i was in there for about a half hour. It didnt hit me or anything, but I know I did have to breathe so of course I had to inhail it. I dont do drugs, thats all my friends, Im usually the one who takes care of them. So my problem is, I have a drug test for a job on monday, just wondering what is the quickest way to remove the evidence. They will either take a blood, urine, saliva, or breathe test. Oh and this party happen 2 fridays ago.
