@Bala Murali,
unsolicited advice, IMO, i would suggest you apply for a job as a technician with any of the pvt airlines in India or MROs.
Rack up (gain) your minimum experience to appear for the Indian DGCA exams. You should be able to get thru considering you have a degree in Electronics and Electrical Engg.
As Yoth mentioned, there is no substitute to hand skills. As a Avionics technician you will be in a position to appreciatiate the application of the theoratical knowledge. If given an option, seek a placement in the Heavy maintenance or hangar based positions. There are MROs coming up in Trivandrum, Hyderabad and Bangalore. The money won't be great to start with however as compared to spending close to £30k over 2yrs in UK chasing a degree in an industry on the decline in UK and EU, you could be half way thru to gaining your Indian AME lic with the possibility of working in what will IMO be the largest MRO country in the world. Middle-East, Singapore, Malaysia have a large number of Indians working in their MRO industries.
Alternatively apply for a opening with ROLLSROYCE, GE, BOEING or AIRBUS. These aerospace giants have significant works @ Bangalore especially GE.
