MSN Careers does not receive any resumes. Most companies will acknowledge receipt of your resume with an automatic e-mail minutes after your resume is received, but it is possible that you won't hear anything at all. When you apply for positions for other sites not affiliated MSN Careers, you may be submitting your resume directly to that career site, the hiring company, or both parties. They may or may not choose to acknowledge receipt of your resume. If the company has chosen to automatically acknowledge your resume submission, you should receive an acknowledgement e-mail almost immediately after you send the resume.
Responses pertaining to the actual hiring process, however, are at the employer's discretion.
Regardless of whether you do single job searches or use MSN Job Hunt , there is no limit to the number of jobs you may view or resumes you're allowed to submit. My search results don't seem to match the search criteria I entered. They may seem unrelated, but every job in a search result does, in fact, match your search criteria. The employer who posted the job chose to display a shortened version of the job's description, and the missing keyword can only be found in the portion of the job description not displayed. The job description contains your keyword in an abbreviated form.
