Engineer

I do not see a reason why pharma and chemical engineers cannot open a drug store. Certifications, licenses and permits are dependent on the laws governing your location. Each state has a board which evaluates pharmacies and grants licenses. You should contact your state pharmacy board for a permit or a license to open a pharmacy store. If you find the laws complex, you should consult a lawyer who is savvy with the laws of the locality where you would like to open a medical shop, and also use them for the necessary paperwork.

Electrical engineering and electrical and electronics engineering are two different branches of engineering.

EE (Electrical engineering) is better for you according to me.

If you get ONGC or any other PSU it will be about 11 LPA. For Esser, Reliance and other top private companies it is about 6 LPA at the beginning.

Hello Niranjan,
If you complete your B.Tech from any of the top IIT then you can easily get an average salary of 8 to 10 lakh rupees and maximum of 50-80 lakhs.

It isn't a major problem as far as your gap is concerned but at the time of job interview, if the HR asks you the question for a gap, you should be ready with a valid answer which should be logical and honest. In my career, I have seen a chartered accountant professional working in the sales department of a private bank. So, you working as a CCR being an engineer should not be an issue but yes what you do you should enjoy doing.

M.Tech is the best option as you have done mechanical engineering. If you want to make your career in the corporate sector, opt for MBA.
