A covering letter is the most important part of your Curriculum Vitae as it reflects your passion towards the job you are applying. An effective covering letter should include your basic introduction such as your name, educational qualifications, and city where you reside.
Further, it must contain the name of the position you are applying for, in the subject field just after the name and address of the person to whom you are applying. All these things must come in the first paragraph of your letter.
In second paragraph, you should state the reason why you applied for this specific job and why the employer should select you. You must state your qualities here and give reason how they are fit for the applied position.
In the last paragraph, you must thank the person to whom you addressed your letter. Put date and place in the end and your covering letter is ready. An updated Curriculum Vitae must be attached to this covering letter.
