Ideally, a cover letter should be 3-4 paragraphs and take less than 1 page.
Focusing on yourself, not on the company needsThe first and foremost question a hiring manager asks is ‘What can you do for the company?’ So, it’s better to show measurable achievements to let him know the result you can bring rather than tell about your ambitions to build a career with the company.Sending the same cover letter to all job openingsHaving a cover letter or resume template is acceptable but be careful and make sure it’s customized for every job you apply for.
Otherwise, you’ll leave an impression that you apply for any job write my resume for me which is always seen negatively by employers.
Try demonstrating your qualifications and their needs for every specific company to succeed.Overuse of clichésA typical cover letter is a treasure box of clichés.
“Please find my resume enclosed”, “Available for an interview at your earliest convenience”, etc.
Yes, they will find your resume and yes, they’ll invite you for an interview – if you catch their attention by non-standard cover letter.Neglecting the proper proofreadingA hiring manager will think that you either aren’t much interested as you didn’t bother to proofread or lack writing skills which are necessary for any profession.
