In case you had any doubt, a Newsweek poll confirms the obvious:

When it comes to getting hired in the first place, 57 percent of managers believe an unattractive (but qualified) job candidate will have a harder time getting hired; 68 percent believe that, once hired, looks will continue to affect the way managers rate job performance. It's a view that's reinforced among survey respondents from the general public, a third of whom are either retired or looking for work themselves: 63 percent said being physically attractive is beneficial to men who are looking for work, and 72 percent said it was an advantage for women.

Also, two thirds believe some managers would hesitate before hiring a qualified job candidate who was significantly overweight, and 84 percent said some bosses would hesitate hiring a qualified candidate who looked much older than everyone else in the office.
