Sent them a perfect CV for the position description, never got back to me.
Later figured out that they only evaluate candidates from the University of Piraeus.
If your degree is from another university don't even bother applying. Seems to be a place without much diversity.
I applied in-person. I interviewed at Velti (Athens, Athens, Attica) in Jan 2017
Interview
I was 2 interview. The was from the phone and the second at Velti's office. It was the most easier interview in my hole life. The company has payroll problem (3-4 months delays ) so they dont have developers at all because every good developer leaving. So if you are not good junior with no experience and you dont care about money (remember the payroll delays)
