Question: Employer's website states:

> 
> If you are interested in a career opportunity with \_\_: mail, fax or
>  email your resume with salary requirement to: \_\_

Do I literally just send the 1 page resume with salary requirement (if I decide to include it)? Or do I need to write them a letter or something too?

Do I need to explain myself / thank them?

Send your resume. And send a cover letter stating your salary requirement.

As always, the cover letter should mention the job you are applying for, why you would be a good fit, and should convey your excitement about the possibility of working for the company.

As @Lilienthal correctly points out, when there isn't a specific job posting, your cover letter would instead talk about the kind of profile you have and how your skills and experience would be valuable for the company

Basically, the employer's website is indicating that they want to be sure you include both your resume and salary requirement. They aren't saying that's all you are allowed to send.

And if you decide not to include your salary requirement, they will almost certainly reject your application.
If that is what they requested, that is all you need.

An appropriate cover letter won't do any harm, but may or may not help depending on how their process works.
