Send Resume And Cover Letter As One Document Or Two. A pdf is the most professional way to include your document, because it is an unchangeable format that looks finished and polished. While it depends on the individual hiring manager, sending it in two files is generally preferable.
The resume and cover letter are two very important documents which present the job seeker to the employer. Your letter may be passed around from one manager to the next, and a printed or photocopied email used in that situation looks unprofessional; So the professional thing to do is have individual documents, one being your cover letter and the other being your resume or cv.
When applying for a job, it is important to know the name of the specific person or people who will review your application.
Some companies prefer attachments, while others prefer it to be in the body of your email message. It seems sloppy and unprofessional. You cover letter needs to work in tandem with your resume. I don't know how to do this.
