Computer Engineer

Hi Shashank,
Broadly speaking, to begin a career as a data scientist, you need an advanced degree in a scientific discipline like Statistics, Mathematics or one of the Sciences and a strong technical background. You also need to develop a deep expertise in diverse analytical tools like SAS, Hadoop and R. It’s also beneficial to have had previous exposure to working with large amounts of data, preferably even some data mining algorithms.
In order to solve your query I would like to inform you that Graduate Aptitude Test in Engineering (GATE) is an all India examination administered and conducted jointly by the Indian Institute of Science and Seven Indian Institutes of Technology on behalf of the National Coordination Board-GATE, Department of Higher Education, Ministry of Human Resource Development (MHRD), Government of India.
M.Tech aspirants can apply for GATE exam as it is an all India test. The test is administered by top technology institutes.
To prepare for the exam your preparation requires the right approach along with the right study materials and strategy. Routinize your day effectively. The preparation requires focused study rather than plain hard work. You need to know what sections the test paper consists of. Know your strengths, work on your weaknesses on start working on it. Start your preparation after gauging your weaknesses.

It's very good that you have figured out what you want to do straightaway. Now you can focus completely on your goal and grow your career in the right way. Since you are interested in Android Technology I assume you have some programming knowledge. And if not then please start learning now and try to Master either C+ or Java.
Java will be my personal choice. After you Master a programming language, rest of the things will be pretty easier. Go for the new Boston videos. They are very good. After that go for learning Android programming from scratch. You can take online courses. According to your preference you can opt for any.
But along with that for now focus on your boards and crack the Engineering entrance exams and get in a good engineering college. Take computer Science branch and be the coolest Android Developer ever.
All The Best.

Adding some more bits to what Abhinav has answered :
1. Try your best to get your engineering degree from a reputed institute. Unfortunately, your salary package and placements opportunity increases exponentially with the reputation of your college rather than your talent.
2. If you want to get into software development, then develop a good command on any one popular programming language.
3. Apart from having command over a programming language, first try to develop a strong understanding of logic building .
4. And lastly, try to develop some interpersonal skills.
I think that's all you need to be on track of having a good software engineer career.
Hope this helps :)
