Now I am doing second year mechatronics after finishing this course what can I do and what are all the things like software I like to learn.

Dear Friend

You are into the excellent technological gamut which is constituted with three dimensional approach like mechanical, electronics and computational engineering. As far as job is considered you will be having tremendous scope and it is you who will decide which brand or which stream or which rd i have to join. Industry will be after you due to the multidisciplinary scope of your degree. Being a student of such dynamic course work you must be inducted into the modules those are being offered to you and this is how you can foresee the employbility in future. Automation and robotic will bring you to the core RD program in advance countries which are manufacturing robotic smart car. Explore the website at the right time.
Mechine vision can also lead you to core automobile company here in india or abroad bothe needless to name any automobile industry like suzuki, maruti, toyota rtc.
Interesting area sensing and contro systems might be part of your study also gives you high exposure.
You can see the future in biomedical systems also where engineer like you is being inducted in emerging technology to equip the physically handicapped people so having experienced with medical sciences, molecular medical sciences, nerve science with the core strength of electro- mechenics and biocomputation you will be on the top where millions are waiting for your contribution.
Such hybrid technology oriented program is much needed to serve the society where science is being served magnanimously.

I suggest you that you concentrate on your study and qualify all the modules judiciously at initial level which is compulsory, at advance level you will be into the internship must strike a module which seems to be very interesting for you and consider it for your thesis work where you can project the max and must give a noble design which could be taken by any rd on commercial level then you will never look back in your career.
So it is very challenging to judge a module where your comfort and interest speaks a lot.

Similarly I see huge scope in structural dynamics and energy and power system where entire world is striving to achieve the relax.
Your goal should not be the monitory gain never commit such mistake in life always focus on your skill which will return you more than your expectation this is the intelligent approach to earn the wealth ans respect both.

Best
