As a person in the process of conversion, I am also "shopping" different movements. The interesting thing here where I live is that the local board of rabbis, which includes every movement, asks potential conversion candidates to attend an 18 week introduction to Judaism course. During this series of lectures, rabbis from each of the movements will teach a class or two, and the classes are spread around to different synagogues.
So far, I can tell you that the young, Reconstructionist rabbi ( early 30s) seemed very influenced by 19th century higher criticism, and as such took a critical view of Torah, miracles, and Jewish history. He was also disparaging of "converts", believing that Judaism is an ethnic and cultural religion only. His lecture spawned many calls to the Board who then apologized for his message to some extent and assured the class that his views are not shared by the majority of Jewish thought.
The Reform rabbi ( in his 60s) was more spiritual, spoke at length about God's role in the history of Israel, believed in the Torah and the Exodus and spoke highly of the Talmud. I was expecting a more liberal theological approach, frankly, and was surprised by how "biblical" he was.Pleasant experience over all.
The Conservative rabbi ( late 30s) is very Tanakh-centered, almost Orthodox in his teachings and observances, very spiritual, yet kind and friendly.I think some would call him "Conservadox", as he is by far the most "frum" Conservative rabbi I have met yet. Very impressed with him so far.
I will post back after the next few rabbis lecture, including the Orthodox one, who will be handling the topics of kosher and halacha. But one thing is for certain, there are many different views and approaches within Judaism!
