How to reduce your recuitment costs?

Look for profiles internally.
Set up recommendation campaigns: your employees know probably the perfect profile you are looking for (Bonus could encourage even more their motivation).
Use cheap tools for advertising your vacancies (Google, Linkedin, Facebook...).
Check available resumes on Linkedin.
Consolidate your network of recruitment agencies: analyse their way of working and their cost structure.
Post and update regularly vacancies on your website, reply to every application and save every profile in a database (Might be useful in the future).
Externalisation of non strategic functions might be very cost effective.
