If you are pursuing B.Tech., MCA or any other technical course, you need to go for Internship or Project Training. The aim of Internship/Project Training is to get exposed to the real world implementation of the things you have studied in your course. During College practical classes, we may learn to grasp the concepts. But the improvisation on the skills, which can make us employable in future, can only be attained through industrial training.
So, if you are looking for internship/project training/industrial training, seek an organization where you get the opportunity to work on live projects. This would be a big step towards your professional career.
