Dear,

IIEST is a good college but placements are better in NITs. Some top NITs are:

1.National Institute of Technology Tiruchirappalli
Tamil Nadu
2.National Institute of Technology Rourkela Odisha
3.National Institute of Technology Karnataka-Karnataka
4.National Institute of Technology Warangal-Telangana

Some NIT's like warangal trichupalli and more are better than IIEST but IIEST stand's tall when compared with NIT which are newly opened or are not so impressive.

Hope this helps!
