I went through what I think was an orthodox giur l'chumrah from 2008-2010. I say "what I think was" because the rabbi who referred me to the Beit Din told me that it was a giur l'chumrah. I don't remember the Beit Din saying anything about that though.
The Beit Din never asked me to change my name or to choose a Hebrew name.
Although I met with the Beit Din on multiple occasions and the entire process took about 18-months (which what felt like a very humiliating process at the time, considering that both my mother and her mother are/were Jewish), no one ever asked me very substantive questions on halacha (during one meeting I, without prompting, gave a very short drash on that week's parasha, which was the most "technical" that the conversations ever seemed to get). So, it seemed like the meetings were a sort of formality, but the fact that the process took so long made it not seem like a formality...it was confusing.
However, they did want to make sure that I was shomer shabbos and kept kosher, so they did ask very rudimentary questions about how to observe kashruth and Shabbat, both according to orthodox standards. Yet, there was no oversight (at least that I was aware) as to whether I was actually living an observant life (just to note: I was).
I also didn't regularly meet with or study with my rabbi (or any rabbi for that matter, although I continued to study with my rebbetsen), who was also the rabbi that referred me to the Beit Din (and I doubt that he was "reporting" back to the Beit Din as to whether I was attending services, studying with his wife, wearing a skirt, observing shomer negiah, etc.) So both of those differ from a regular conversion, at least I assume.
The Beit Din also wanted to make sure that my Israeli-born, Jewish-on-both-sides fiance was wearing tefillin each day.
Definitely no one reminded me that it was my last chance to change my mind when it came time to immerse.
If I recall the brachot...I made the regular t'vila bracha, then I'm pretty sure that I said a bracha that included the word "stranger" (ger, in hebrew of course, so I suppose this would be the conversion bracha), but I did not at any point say shehechayanu.
I know another woman who went through a giur l'chumrah on the East coast and her process also took some time.
When I found out that I had to do a giur, I was told that it was specifically a giur l'chumrah, that I would just have to read some books and then meet with the Beit Din and immerse. I had heard of regular conversions taking a long time, but it seemed, or so I thought, that the giur l'chumrah would be faster. It wasn't. And at no point in the process did I know how long it would take. I just basically had to wait. It was absolutely horrible, especially since I was engaged at the time.
Also unfortunate was that the rabbi marrying us made sure that my ketubah referred to me as a giur.
Also no one dissuaded me three times. Isn't that a thing with regular conversions?
