You have done your B.Tech. about 6 years back. You have not indicated your occupation during this long time. That is required by us to know about your experience and proficiency in a particular area before we suggest certain career paths at this juncture.
Anyway, in absence of that vital information I can mention some options to you and based on your capabilities and experience you can think of pursuing those career lines for yourself.
As you have shown inclination for IT/ computer areas, first I will take up this. In this area a lot of advancements have taken place and there are various entry levels depending upon the skills one has acquired.
The basic level is for routine computer management and office work like creating documents, excel sheets, presentations etc and managing the files in computer for quick retrieval which is more akin to a digital record keeping job.
For such work a certificate course in Basic Computer Course will suffice.
If your potential is higher then you can go for courses in web design, software languages, system management, repair and maintenance, JAWA, software testing, TALLY, digital marketing, VFX and animation etc. You have to pinpoint your interest and aptitude and then go for the certificate or diploma course in the selected branch.
IT is not the only area for career making. There are many different career paths today which can be chosen and pursued.
There is a boom in hotel and travel industry as more and more people are traveling for seeing the places around the world. Indian tourism industry is also doing good. You can consider doing a certificate or diploma course in travel and tourism and join some reputed travel company or even a good hotel.
Please remove the notion from your mind that you are an engineer and can do only engineering jobs. It is not like that. A hard working person can be successful in any career line.
Have you ever thought of working in insurance and risk management area. This is basically a commercial arena but after doing some basic course you can very well apply jobs related to it. There is going to be good scope in this niche area in future.
What about joining a business house where there are jobs related to management of inventory and sales. This does not require any specific skill. With experience you can learn the tricks of the trade and can start your own retailing or supplying in future.
If you have some interest in commercial area then doing a quick course in GST will give you an edge to apply in various business entities.
If you have got interest in teaching then you can think of joining tutorial institutes and if your proficiency in teaching is established, you will be a sought after person soon.
I want to mention that whatever line you choose for your career, take it seriously. Today there is a lot of competition and people are excelling in all the areas. One has to be very hard working, dedicated and focussed for his goals.
Knowledge is power.
