As a reminder, here is what the Greek political landscape looks like currently (much more here):

As Credit Suisse explained earlier this week, this is the procedure:

The election result will be known late at night on Sunday 6 May. Following that, if no party has the majority of the votes (which is the most likely scenario), the president will ask the leader of the first party in votes to try to form a government (e.g. through a coalition) that enjoys the confidence of the parliament. If this fails or the party withdraws from its right, then the second party is asked to do the same and so on. The process is repeated for the three largest parties and each one has a three-day deadline. If these attempts fail, the president calls the parliamentary leaders of the parties on a last attempt to form a broad coalition government. If that is also unsuccessful an interim government is formed that would lead the country to a new election within a month
