I moved down from the DC area about 5 years ago and have experience applying for jobs from states away and locally. It was hard applying while away as I feel in this market you really need to do more than submit resumes (i.e. informational interviewing, networking, taking meetings etc). That is harder to do from states away though can follow up via email and do phone follow up etc. Atlanta is a vibrant city with many large educational institutions (Emory University, Georgia State) and large companies. What kind of role are you looking for in Atlanta? It is a great city and I highly recommend it to anyone.
