Stewardesses' recruitment

Mar 23, 2009
Hello to anyone who may read it!
I'm currently doing a research on Titanic's stewardesses and I have only found little information on their recruitment so far.

*I especially wonder how the stewardesses were recruited; I've read about a lady superintendent choosing among the candidates in Cunard, was there the same position in the White Star Line?
*They must have come with their personal details if they weren't already on another White Star vessel, but the new employees may have a letter of recommendation -especially in the case of V.Snape-. Does anyone know if some of them still exist?
*As most stewardesses came from the Olympic, did they still have to go through the whole recruitment process or was it quicker for them?

Thanks very much in advance for any help!
