Not able to get interview calls

Have been trying for almost 2-3 months now. Luckily have got calls from accenture, deloitte, kpmg. Completed their interviews but haven't heard anything from them. Updating naukri everyday, applying directly, asking for referrals, etc. 90 days notice is also a problem for me. Any tricks to follow to get more calls? Have 2.6 years of exp.
