Where do you fit in your current organization?
Take into account your compensation range and how you compare to peers with similar titles with similar years of experience.
How much responsibility do you have?
Would you like to have more? Do your peers have more or less?
Are you being promoted?
Are you moving up at the rate you would like? Have you been given opportunities to grow within your current company?
By taking stock of your existing situation you can then have a better understanding of where your opportunities might lie in the future.
Are you happy with where you are now? Why or why not?
