Hi Sunny!

If you have a good Score expected by the recruiters and perform well in the levels they test like Group Discussion, Personal Interview, etc,. then you will definitely be recruited by the Companies! If you are asked about the gap in education, tell them your genuine reason. If you feel your reason will not be genuine from their point of view, then tell them that you wanted to follow your passion and wanted to study Mass Communication and hence you left Engineering. But, try to be honest with your answers because sometimes that would attract your recruiters!

Hope this is helpful!

All the best!
