1) Circumcision (for uncircumcised males)
2) Acceptance of the Torah and its commands: to intend to live as a Jew
3) Immersion in a ritual bath (mikvah).
In practical terms, the conversion is done with the knowledge, supervision and help of a beit din (Jewish court); and the prospective convert learns about Judaism before converting. Those who seek to become Jewish are (at first) discouraged by the beit din, until and unless it becomes clear that they know what they're doing and are serious and sincere about it.
People join Judaism for various reasons, including spiritual seeking, a desire for community, and a connection to Jewish culture and history. Many are drawn to Judaism's rich traditions, ethical teachings, and emphasis on social justice. Some individuals may also join through marriage or family ties, while others explore Judaism as a path for personal growth and identity. Ultimately, the decision is often deeply personal and multifaceted.
The major modern Jewish sects are: Orthodox Judaism, the most traditional, which attempts to follow the Torah explicitly; Reform Judaism, the most liberal, containing 42 percent of American Jews; Conservative Judaism, between Orthodox and Reform, based on the teachings of Zacharias Frankel; and Hasidic Judaism, which promotes internal mysticism.
Read up on the religion and see if it's right for you, then talk to a rabi at a local temple. Not really that much that goes into it.
In fact, Judaism was the first source (the prime data) for Islam, and, in fact, there was a very early attempt to join the two. But currently that fact is being largely ignored, and for MOST practitioners of both faiths, only the differences between the two seem to matter.

There are no rooms in Judaism. Judaism is a religion, not a building.
Judaism is called Judaism.
Opposite of the lack of Judaism? Judaism.
Most religions, including Judaism and Christianity, do not like it when you leave the religion and join a new one. If you know anything about your faith as a Christian, you will know the answer to this question.
Judaism's real name, in English, is "Judaism".
