First, write a general statement about the job you want. For instance, " I am an experienced marketer looking for a job in sales." Now you have something to work with. From here we will be adding and fleshing out this basic statement.
A couple powerful adjectives will do wonders. Instead of "experienced marketer" say something like, "innovative salesman with over 10 years experience," or "creative and market-tested professional." Give a potential employer a strong first impression.
Next you need to include some targeted keywords and phrases. This is of vital importance as many companies will use scanners that hunt for these words. To stay with the above example you should say something like, "creative and market-tested professional with experience in cold sales, staff leadership and key demographic development..."
Write exactly what you are looking for! Now you need to come right out and state the position you are going for. If it is posted as a "Sales Manager" then write the words "Sales Manager" in bold as part of your objective.
Finally, you need to include the type of company you would like to work for using some flattering language. "A creative and market-tested professional with experience in cold sales, staff leadership and key demographic development seeks a Sales Manager position in a fast-paced and growing firm that values tam work while rewarding individual achievement."
With a powerfully written resume and cover letter your chances of landing an interview are greatly enhanced.
