Online submission of the job application.
In my case, they found my CV through a recruiting company.
A phone interview was held by the HR of the company, because he was away at that time.
Two days later, I had a personal interview at the HR premises in Athens (and a computer test on Microsoft Excel skills - a test which hadn't been mentioned before).
Then, about 10 days later, I had a personal interview at the relevant Division.
I received a (negative) answer through an e-mail (with a 3 days delay).
Positives: friendly and quite informal atmosphere during the interviews
Negatives: the vacancy posting had some spelling errors and they delayed to give me a final answer.
Also, the fact that I wasn't warned before about the computer test at the HR premises.
