Resume advice is changing. Advice like: send a thank you note (yes!), don’t lie on your resume (big no, no) and make sure your resume is no longer than ONE page (ummm?!?).
The one page thing may not be the best advice anymore! With more hiring done online, the one page rule is OLD. According to hiring managers/HR longer resumes show you made a real effort to apply for the job. Most good resumes are now two pages. Bosses say the more details, the better. Happy resume writing!
