The half life of Klonopin is 19-60 hours, which means that it can still, theoretically, remain in the system for up to two weeks. However, I'm not sure that most employment drug tests test for benzodiazepines, and if you have a prescription for it, you should be good. I will assume you do not (or else you probably wouldn't need to ask), and just throw in that if you are using it recreationally (which is obviously contraindicated), don't drink when you do. Bad mix.
