Cover Letter (Part 1): Is it important?
A good cover letter is essentially a sales document, consider it as your sales pitch that you should design to convince the employer of what an asset you will be to the company.
When designing a cover letter, remember the employer is probably receiving hundreds of applications for any one job. They will be stressed out and very, very busy. You have a window of opportunity of no longer than 30 seconds to convince them to take your application to the next step and read the CV.
Remember, “A good cover letter doesn't guarantee you a job, but yes, if done wrong, IT CAN COST YOU THE JOB!!!”
