Second , up-skill your self with some more job oriented courses like Web or mobile app development. Just don't depend on the courses you have already done. This will actually help you to get more opportunities.

Check this Facebook group to get details on Job openings:-

Apply to all the walk-ins and openings of fresher levels. Connect with your friend circle, seniors and relatives working in industry. Ask them if they know any job opening.

Stay Positive and Keep Learning,
Vikram
