Hello nihal

I have read that IET lucknow is a legacy college and it's great placement for core branches like ECE or CSE most of the students get placed at a nice package some have even got 8-10 lakhs placement but the average lies between 3-6 lakh per annum  i am providing you some links where you can read about the placements and review about this college from the students themselves
