Can anyone help? Unit 333 Recruit, Select and Keep Colleagues

[Lucy]

Hi everyone
Has anyone completed this unit??

I am really stuck on the following

333K15 - How to review the effectiveness of recruitment and selection within your area.

333K17 - Recruitment, selection and retention issues and specific initiatives and arrangements within the industry/sector.

333K18 - Working culture and practices of the industry/sector.

Any help would be absolutely great, been banging my head against the wall since 7.30 this morning!!
