The issue is not the baptism, but what you believe. If you believe in Jesus as the savior, and the Trinity, then you are fully Christian even if you had been born Jewish (though you could later renounce that and return to Judaism).
If you believe in Judaism and do not believe in Christianity (or other religions), you are Jewish (though you would also need a formal conversion to Judaism if you had not been born Jewish).
A Jew who underwent baptism but does not believe in Christianity has not changed from being Jewish just because of that ceremony alone.
Other information
Judaism does not proselytize or seek converts, but it does accept sincere converts.
Conversion is a life-changing and very serious undertaking and a potential convert should think it over carefully. It must not be done on a whim or because of temporary circumstances. One who converts is expected (from then on) to live as a Jew.
The first step would be, without outside help or influence, to get to know about Judaism. The person who felt interested should hang around a Jewish community in order to get a sense of whether Jews and Judaism as it is actually lived appeal to him/her. Also to do some reading. English-language books on Jewish thought and life can be found in Hebrew bookstores.
After that, the interested person would approach a Rabbi and ask about enrolling in a relevant formal course of study. This can last for several years and is an integral part of the process, since he/she will have to actually practice the religion.
Once that is completed, the convert immerses in a mikveh (ritual immersion); and, for uncircumcised males, undergoes circumcision.
If you were not born Jewish, you can convert to Judaism, regardless of any previously held religious beliefs or practices. But you would have to renounce those non-Jewish beliefs (among other things).
