Thanks for the advice (some of you!) the stubble will come off, for the interview anyway.
What i forgot to mention though, was i dont like to clean shave because it irritates my skin severely, i can use all the cooling balms under the sun, they just don't work for me. anyway i'll endure the suffering for the interview and hope i get the job!
..and for whoever asked the job is Refridgeration/Air Con installation and repair.
