No...
What a job wants is for an employee to be professional, so I think you'd be better off just coming in without the tail.
For a non-fur, no matter what job you're going in for, wearing a costume to work would be considered silly, and it would be hard for them to take you seriously.
I think it would be a slightly different story if they already knew your talents and work ethic was good and you came in with a tail or even paws on, but even then it would be a bit iffy...
