And so far whatever I have researched I found Big Data is the demand in IT sector. 1. Can a non-IT guy with no programming/coding knowledge can step into Big Data? 2. How much scope does Big Data have or for how much years can we except Big Data around? 3. If I opt the course into your institute, will there be any real-time exposure during the course? 4. Can I easily get a job into Big Data as I am a non-IT person? And any experts or who have already taken course from any Institution and got helped in getting placements, please do suggest me which would be the best.
