2.Business Etiquette 

3.The Basic CV Writing format which is important  in understanding the person you are Hiring 

The recruiter would firstly enquire about the primary details to the candidate. If that is alright, then it comes to the next stage where the recruiter match the candidate's CV with the job description for the particular vacancy. Then several candidates are short listed and from which a single eligible candidate will be selected after several tests aiming to be precisely needed for the job vacancy.
