As I have posted to other threads concerning resume critique. I have decided to create a general post concerning resumes. These are general things I have used, told and seen with great responses:
1. Make sure that the text in the body of resume is at min 10 points but no larger than 12 points- arial or new times roman.
2. Use bolding for each company and title that you worked for
ex.
JOHN DOE TECHNOLOGY
Widget Admin
3. DO NOT USE an OBJECTIVE on the resume at all- reason being as it creates you having to reedit the resume for any job applied for and is very limiting.. it is far better to use a SUMMARY statement to give a brief into to what you have been doing -- the resume body will complete this.
ex.
Experienced IT professional with 3 years of Widget administration. Blah, blah, you get the idea.
4. Certifications- when you have a couple (1-2) its ok to but the vendor stamp/emblem on there cisco, comptia, ect.. but when you have a few (3-5) its far better to list them under a seperate heading
CERTIFICATIONS
you still want to do this listing even if you have 1
5. word repetition- be very careful using the same word consistanly on resume this can bad.. at best try to use a different word or sentences from job duties to job duties.
ex. insured the proper installation of network gear
performed equipment installs to company guidelines
6. Make the resume pleasing to the eye and easy to read.. alot of resumes get overlooked due to this. try to make the layout and flow of the resume simple and easy to read not to you but to someone that doesn't have a clue as to what you do.
7. NEVER put references on the resume or references available upon request.. if they want them they will ask for them
8. It's ok if your resume flows into 2 or 3 pages as long as its concise.. at min keep 5-6 employers especially if a part of the same lineage try to use the longer term gigs also...
Not any 1 to 2 week deals and be sure to list if it was a contract and the term of the contract and state if it was completed successful to the term.
9. Be sure to list your up to date email address( this would be one that you check often) and professional address
ex. [email]keenon.example@???.com[/email]
and not
[email]hotbody@???.com[/email]
Also home and cell phone number (with no crazy ring tones and messages).. and no work numbers.
10.  This is just a side piece if a job posting is out there and you have 3 out of 5 things they are looking, for apply for it.
Any addtional info I will add as questions arrise. If any of the info helps you start generating more possible employer contacts please post.
NEWLY ADDED
11. Qualiifcations- in certain cases this may be good but for a technical resume its deemed very bad.
why- your describing something to someone reading your resume and from it they will have to decypher your skills to see if your a good fit for the opening.
instead- use a skills listing be very clear about it
ex. familiar with configuring cisco routers
helping build windows server

 Cisco router models (800, 1600, 1700... u get the idea

 MS Server Products
these are possible but look at the job description to get a more better idea
12. hobbies- this is something that if they want to know they'll ask in the interview omit it from your resume
13. interview follow ups-
many have opinions on this but from my own experience i have learned
not to send a thank you letter/email until a few days afterwards-- reason they may have more interview to complete and you don't want to seem too needy. .besides if you send it in a few days it joggs their memory and if you had a good/great interview it only adds to them keeping you in the top
3 candidates as well
if calling follow the same rule, if their busy keep it short
" i wanted to thank you for your time speaking to me on ??? and i hope to hear from you again"  to that effect and get off the phone don't ask for a call back and don't call back- unless they ask you to get the time and keep it.. when calling back remind them of it " i was giving you a call back in reference to ....."
if they're not busy keep it short as well but if they want to discuss it further do so.. ask any questions that you have left over
I have another post which i'm throwing recruitment emails that i have received from my own resume that aren't interesting to me.. so i must be doing something right
