After an election, the president meets with the leaders of every party that won Knesset seats and asks them to recommend which party leader should form the government. The president then nominates the party leader who is most likely to command the support of a majority in the Knesset (though not necessarily the leader of the largest party/faction in the chamber). The prime minister-designate has 42 days to put together a viable coalition (extensions can be granted and often are), and then must win a vote of confidence in the Knesset before taking office.
