It is the unfortunate reality that you may be discriminated against by a potential employer, be it race, weight, marital status, looks or something else superficial.
Putting the above said information in your CV including mugshot merely makes the rejection process happen much faster. If you get to the interview after travelling half way across the country you'll be more disappointed to find out that another guy who is better looking and weighs 20kg's less than you with the same experience got the job. This is called REALITY.
The interview happens when you meet the required criteria and the employer wants to know if you are an alright guy / gal.
