According to Careerbuilder, exceptions can be found [1] in most job search rules. . . with one glaring exception. Typos on résumés are never acceptable, no matter what job you're after or how much you dislike spell-checking for errors. Here are six rules that Careerbuilder says can be compromised, and to what extent exceptions may be made.

1. Keep your résumé to one page. Exception: For job seekers with five or more years of experience, one page simply might not be enough.
2. Never try for an interview with a company that isn't hiring. Exception: There's no harm in setting up an informational interview with someone at the company where you're dying to get a job.
3. Avoid sending a résumé with fancy formatting. Exception: If you're applying to a creative position like graphic design, you may opt to send a résumé with an atypical format.

4. Don't apply to a job for which you have no experience. Exception: Employers tend to go with their gut when making hiring decisions, so if you have a personality that would make you a good fit but not the technical experience you may end up with an offer anyway.
5. Develop a pitch to market yourself to employers. Exception: When an employer says, "Tell me a little bit about yourself," tweak your response to the situation and the person rather than give the same scripted response to each interviewer.
6. Never say negative things about your previous employer in an interview. Exception: Only share negative details if they are factual, like if you left your last job after a short time because your boss invaded your privacy.
