There are many add on courses which can be taken up after completion of the engineering degree. These courses will help an individual to get the job in those specialised areas.
One thing which is important at this juncture is to identify your interest and aptitude and accordingly select a course. One can always excel in the field of one's liking. There are many options for these courses. Certificate and diploma courses in computer and software area is a good option. You can think of doing that in System Management, Repair and Maintenance, Database Management, Networking and System Analysis etc.
If you are inclined towards financial and managerial line then you can think of going for courses in Finance and Accounts, Office Management and Automation, Basic Financial Management etc.
There are many other streams which may appear to you away from your core area but they deserve mention as they have potential from job point of view. Environmental Science, Safety and Security, Handicraft and modern garments, Insurance, Archive Management, Instructional Designing, Chemo Informatics, Retail Management etc.
Another important thing is do not shy away from a small job having small renumeration. The reason is quite simple that it may be a small job but it will provide you a quick experience in less time and that will go a long way to help you to switch your job to greener pastures.
So do not feel discouraged and demotivated. Today the job position in our country is really very tight and competitive and one has to do a lot of hard work and efforts to carve out a career.
Knowledge is power.
