I applied online. The process took 2 weeks. I interviewed at Generation Y (Athens, Athens, Attica) in Nov 2017
Interview
2 interviews within a week both on Skype (I was working abroad). 1st one with the HR manager and the CEO. The HR manager was playing with her hair and looking at her phone and the CEO answered 20% of my questions and insisted on letting me know that they are "champions" amd "the best company you can work at in Greece".
