I don’t think it will matter that you had a charge for marijuana; however, I do believe that any felony will give them pause. Whatever you do, be HONEST on the application where it asks if you have any felony convictions. i have several friends who have commented that they were stressing over letting someone go because they lied on their application. Each commented that IF the person had answered the “felony” question honestly that they would still be working for them. Just be prepared to answer a few tough questions about how & why you ended up with a felony!!! Getting a misdemeanor for marijuana wasn’t that hard to do, but a felony charge indicates that you were a big time dealer/user.
Your past is what it is & face it with style & grace. Be honest on the app, answer their questions as to how or why, & then you can do no more. IF you don’t get the job, there just might be a better one down the line & you will be glad it turned out like it did!!!
GOOD LUCK!!!
