Avantages
Strong resume builder --- opens many doors; you will definitely work on some cutting edge marketing programs, and see how marketing absolutely impacts sales. You will also learn in-depth how grocery store marketing operates very differently than broad consumer marketing programs, and learn how to bring the two programs to common ground.
Inconvénients
"every person for themself" --- this is not "we will do it as a team" environment, but rather "this was my idea and I'm claiming all the glory." Unfortunately, some very good people are stepped on, and in order to rise above, you will be dedicating your life to the company. Work-life balance is lip-service, where HR programs in place to create harmony and balance are not relevant to those in marketing.
