Pankaj, I am not sure how good you are with maths and programming. If you are, then you must pick up Programming and take a language whether PHP/ HTML5 (web dev), .Net (for software dev) Java/ Android (for apps) or C#/ Unity (for games). However like i mentioned, you must be good with programming to move ahead in this area since you have to compete with MCAs and BTech(CS) applicants. So choose your internship/ industrial training very carefully. Do not just go for the cheapest to save money. See the IT company's credentials on the net. for example if someone provide LIVE PROJECTS are they there near the TOP on PORTALS like JUSTDIAL? Or if the company is registered with STPI (Software Technology Parks of India) - all good IT companies are registered with STPI. If a company spends money to market themselves to customers, only then they are able to get LIVE PROJECTS. Also, if you are an average programmer, and if you you're better with creative work, then you can head for web design or even vfx/ animation since there is a huge requirement coming up in that domain. There is also an intermediate path in games design and development. Wish you the best for your career. Remember, your Career is a resultant of your knowledge combined with your passion and expression ability. If you like this answer you may select it as best answer or press like.

Hi Manish,
There are various courses related to Computer software and application it generally depends upon your taste of interest.
Some of the certification options are:
Java/J2EE - The server side software development of web is mostly done by this most secure language option. Most of the banks in India and abroad implement their web applications using Java/J2EE only.
.NET - This is among most popular languages which are direct counterparts of Java. These are mainly used for light weight application development on the server side and client side. .NET is also easy to master compared to the long Java Library.
The other options for the courses include, i am listing most prominent ones from job point of view:
Oracle/Mysql/DB2/DBA - This is one of the most reliable course options but you will not get any work of software development on its basis, yet you can continue doing it if you have interest in DBMS.
CCNA/MCSE - These networking certifications can employ you as a network engineer and again even in the recession period these were the most reliable career options, if not most exciting.
Between java & .NET i would suggest .NET and you being from ECE branch, Networking courses like CCNA should be easier for you.
Here is the list of certification courses which one can pursue after completing their graduation:
