When you are creating your resume, you don’t need to put every random job you’ve ever had. What companies do is they look at your jobs on the resume, and at most call the employer and ask them if you worked for them and how you did at the job.
There is no way for a non government employee to know if you worked other jobs. Keep off any jobs that you worked at for less than 2 years and use every skill you learned as a skill for your resume.
Nothing hurts your resume more than having 3 or 4 jobs in a span of 2 years because it shows you are unreliable.
Omit jobs held less than 2 years? In this economy? They’re all less than 2 years! Props to those who’ve held jobs for several years because you must be comfortable. Most people shopping aren’t comfortable and changing jobs has gotten me more money than any in-house raise ever did.
