Hello

IET Lucknow is good and have a great reputation in state . Yes for IT  and cse placement is almost same . Around 70% of student get placed in cse and IT branches. Both the branches offer average salary package of around 4 lakh per annum.  Here most of the companies visiting are IT ,but cse can opt for that. Tcs ,Newgen are mass recruiter,Adobe comes but recruit only 3 to 4  students amd offers package more than 10 lpa .

Good Luck.
