A presentation by Ms. Shailaza Singh


Neelkanth Publishers recently organized a campus placement, drive, which was the first of its kind  in Amity University, Rajasthan which was attended by a multitude of B.Tech students from various branches including Mechanical, Computers, Electronics and Telecommunications and Electrical. Most of the students had no idea about what publishing involves or how they could get into this field. A presentation and discussion helped them to understand the numerous opportunities available in the field.  A technical test and a proof-reading exam was conducted to test the subject knowledge and their understanding of the minute nuances of the language. This was even more encouraging for many since they realized that they could spot and edit mistakes with ease. More than thirty students were shortlisted for different profiles.
