| I hope you're not doing charity work just so it looks good on the CV. Changes are that, if you are, you'll be rumbled in short order. The 'something extra' does not come from arranging your CV to tick all relevant boxes it's more about you as a person.
I agree 100% with AMiller, most importantly be yourself.
In the long term, and if you have a few years to spare, do an MBA. |
