Weed and new job! Omg freaking out!

I haven't smoked weed in years. 2 weeks ago (on Monday). My husband new and it was ok. I've turned down friends before, but that I said sure! I didn't think anything of I'm a stay at home. I filled out some applications for holiday jobs. I got a call back for interview. I know this I a reputable corporation and I have a drug test! I've NEVER failed a test before and I really need this job. I know if you smoke it'll take about a month, but this was once! Will it be out of system within 2 weeks???
