The placement department of the college is very active and co-operative. Some of my seniors and batchmates got placed with the promised package. Even I got the opportunity but then I tired by myself for something more and got the higher package. The average package offered is 6LPA. But the good performers have a chance to get the placement of around 10 LPA to 15 LPA. Overall, in the end, it is always the efforts of both the students and the faculty members.
