Hi Shiva,
As mentioned by many, we have so many techniques and tools to achieve our recruitment targets. In recent times, keeping the current inflation and, more importantly, attrition in mind, HR executives have come up with the most innovative ideas. Advertising on social portals like Orkut, Facebook are a few of them. Apart from these, we have LinkedIn, Silicon India, Yahoo Groups, which are a few professional portals where job adverts can be placed. However, we have some limitations as no portal is 100% efficient and effective. We can place ads in free classifieds, mass mailing to all these candidates in the same line of activity, internal references or buddy referrals, recruitment firms. One way to attract references could be through ex-employees who have worked with the organization. Maintain and update contact details and keep sending emails to all those about various vacant positions and also send greetings to all of them for New Year and other happy occasions. This will build rapport and keep the momentum going for long.
Hope the above will be of some use to you. I wish you all the best.
Regards,
Suresh
