They say it's a different world altogether out there in the industry. But it's true that the real life challenges posing the industries in all domains are much more daunting than the ones we do within the confines of our lab.
So does that mean your education in a waste. No, we never said that. After all it's the same principles that are applied in solving industry problems.
So, solve some real industry challenges and show them what a true technologists and enginner is!
Please note that there have been a few changes in the problem statement.
