Keep it simple.
You so not have to include highlights from jobs that weren't your favorite. Take words out that aren't relevant to what you are looking for in your next position.
Have a couple of resumes styles available.
Having a more in depth version of your resume is great for you to keep track of the details of your former positions. Do hiring managers need this? Maybe, maybe not. Better to be prepared.
Have your response prepared.
Between every job, ask yourself, why did I leave this position? Have that 'response' prepared for your interviewer. Stay positive when it comes to short stints. If you were new in your career, say that. All your interviewer wants to know is that you aren't planning on leaving after 8 months when you are finally trained for this new position. Don't forget about your current role.
It is a lot of work, but once you figure out what you really want to do, it's worth it!
