if youre not sure, just take them off for the interview
It depends upon the viewpoint of the interviewer.
I'd lose the plugs, especially if the job even approaches the corporate realm. The plugs are pretty seriously counter-culture and honestly, most jobs aren't and almost no management positions are. I once worked with a young guy with fairly big plugs and often thought "gee, what's this guy going to do for a living when he grows up?" I mean, do you see them with a suit and tie? No... Best of luck.
I guess it would depend on what business you are in. If it's the kind of thing where no one cares then go ahead. I'll be honest, I think those plugs are just weird.
