If i smoked pot may 31st and had a mouth swab drug test June 21st will i pass?

Okay so May 31st my friend and I were hanging out at my house relaxing after some graduation prep activities and smoked a bowl. I don't smoke often, it was probably the 3rd time I've ever smoked. And june 21st I took a drug test as part of an interview for a job I rly need. It was the oral swab type test where I help the test stick between my cheek n gums. I don't drink a helluva lot of water, but what are my chances of passing the drug test? Pls I need help
