Depends upon the employer.
First up, no you won't be paid in the hold pool.
Most airlines will pay you from day one, unless, it is someone like ryanair, when you arent paid to start, and then go onto half pay. Details readily available on here via search.
Other airlines may require you to do a type rating with them to get the job, probably same story, only get paid when the type rating is finished.
If you are getting an airline job with 200hrs, chances are you will be on some sort of sponsored course, so I wouldnt expect to be on full pay asap....
