How i can attract the candidates to the job through various portals?

I am an MBA student now i am doing my internship. I wanted to know how i can attract the candidates to the job through various portals and do tell me the name of the portals. and are these portals free?

Your quarry is not clear. If you read your question it means that you want to attract candidates for job opportunity? Are you in some placement service? Your English hardly it befits a stature of a MBA Student

thank you for your reply Mr alexander
i have been selected as an HR intern in a company so i want to know the portals through which i can hire candidates.

Dear Anonymous,
Standard of English is poor.
Alexander is Alexander -please use capital and i is I.
Sentences start with Capitals.
Basic grammar needs to be adhered to for good presentation of your query/case etc.

Hi,
PFB list :
1. LinkedIn (The best platform to attract variety of candidates for recruiters)
2. Freshersworld
3. Facebook (Search job groups related to your industry)
4. Twitter
5. Glassdoor
Thanks and Regards,

Thank You Mr Akash Sharma For providing me the list of portals.
And also Thank you to Mr Nathrao for correcting me.
And Mr Alexander I would like to correct you that it is a "Query" not "Quarry".
Thank you all.

Dear ANNONYMOUS.
Mr.Alexander with good intention tried to correct you but you have taken it in a negative way. First of all please look in to the dictionary and understand the difference between "Query" and "Quarry" then you will know who is right. Being a student (HR Wing) you should focus on your learning and be cool wrt your emotions. Be positive.
Please feel free to specify the areas where I also need to correct so that I can because I feel that till my last breathe I am a learner.
Regards
Kamesh

Thank you Mr Kamesh.
And I feel sorry on my misconduct to Mr Alexander.
