How to search for a job ? I am doing B.TECH.IT final year?

In addition to the first response, there are many ways to search: using job sites, applying to businesses where your skills can be put to good use, and physically, as in going into stores or offices and asking to hand in your CV to the manager or most senior member of staff. If you don't have a CV, use template or ask people you know that have jobs to have a look at theirs.
