great post, though i disagree about a few things
1 - the shirt/tie comments. nothing wrong with a navy tie with a navy suit, paired with a white, gray or light blue shirt
2 - jewelry with regards to religious affiliation is ok, just not to the point of classlessness (rosary/crucifix etc on the outside of shirt etc)
3 - break should only be a HALF in pants IMO
4 - no pleated pants! it's 2011, and pleats only make you look old/heavy/sloppy
5 - you don't have to go online to find a properly tailored shirt. buy one at a dept store or online, then go to the nearest dry cleaner and ask them for tailoring services. usually getting a shirt fitted won't be more than $15 and they can make a $20 shirt look like a $200 one
6 - deodorant.
7 - NO GUM
8 - be careful with teeth whitening. it can make you look absolutely ridiculous. a better call imo would be a professional cleaning from a dentist (should be 40-90$) then brushing and flossing 2x a day for upkeep. be careful with coffee as it can stain the teeth
9 - dress socks only! no white socks! i actually try to match my socks and my dress shirt, but if you are sporting white try to find a neutral color or match your suit
10 - be confident! it's an interview both ways, you need to see if you fit in with them also. keep the posture straight, look people in the eye, shake hands hard and smile and relax!
but remember that, even when those who move you be kings or men of power, your soul is in your keeping alone. When you stand before God you cannot say "but I was told by others to do thus" or that "virtue was not convenient at the time." This will not suffice. Remember that.
