The Indian Institutes of Technology will blacklist companies that hired students this year, but changed their offers later, the All-IIT Placement Committee has decided. Besides, firms that go back on their promised compensation packages will also be barred for one year.

"There are three kinds of companies: the ones that withdrew offers completely, those that have cut compensation after their initial offer and the ones that have deferred joining dates. There are five to six companies in each category," said IIT-Madras training and placement adviser V Babu. He added that the decision was taken because such instances cause a lot of anxiety among students.

Companies such as e-tailer Zimply, healthcare startup Portea and grocery portal Pepper Tap fall under the category that withdrew their offers and thus have been barred from participating in future placements this year, the Times of India reported.

Five students at IIT-Guwahati were denied jobs at Zimply even after they received their offers. Similarly, at IIT-Bombay, Portea and Pepper Tap withdrew their offers made to seven students in February.
