I see lots of you are arriving here and looking for jobs, I decided to name some of the most popular sites that may help you
1. My personal favorite : Skywalker MOST jobs are posted in Greek there are some in English also
2. All in English, try the Athens News Classifieds section: Athens News Classifieds -there are also Appart. Rentals etc.
3. Jobs Abroad site : (English) Jobs Abroad
4. Just Landed site, contains lots of job postings and help with moving/studying and living in Greece : Just Landed Greece Jobs
Hope this helps a few
