I'm a Mormon, and everyone knows Mormons are famous for missionary work, as pretty much every faithful young man will serve a 2 year full-time mission right out of high school, and many women will choose to serve one (or more) 1.5 year missions.
I'm very familiar with the LDS missionary program, but I'm not too familiar with many protestant programs. LDS Missions are pretty simple I think: You go through the application process with your bishop, if he thinks you're worthy then your application gets sent to church headquarters, a few weeks or months later you get a mission call to go serve somewhere in the world for 2 years (the church chooses where you go), you're set apart as a missionary–at which point you start living very strict mission rules 24/7–just before you report to the Missionary training centre for 3-12 weeks prior to being sent out into the field.
As a missionary you commit yourself 100% for 2 full years teaching people about the restored gospel of Jesus Christ, no days off, no vacation, no TV or cinema or entertainment of the like, and no phone calls home except for on Christmas and Mothers Day on top of a plethora of other very strict rules (no flirting/dating, iceskating, horseback riding, etc., etc.).
That's a typical LDS proselyting mission. There are many other types of missions that you can choose to go on, but for this question I'm only interested in proselyting missions.
How do some Protestant missions compare?
