I am also studying engineering now. I know how the students study in engineering. Like one day batting we call the process we study in which we only study for one night and simply get the pass marks we don't even remember what we had written in the exam. If we talk about project then many just simply buy them or ask some one to do. In this way how a graduate person had skills to get employment by this way of studying. So more over it's had to get job without skills even if he get the job then it is really hard to sustain in the job.
The worest thing is in India mostly we have bi polar system like if you can become only one doctor or engineering from the starting stage that is the most weird part.
The second thing is graduation is not enough for employment. Skills were needed. In this present situation it was so easy to get a engineering degree and seat in the college. Which made in every 5 graduates there is a engineering graduate in India .
There are many who got job by their skills not just by simply studying engineering.
