My brother is studying IT at IIIT Allahabad. So, I know about the placement at the institute. 

Over the year the average CTC offered at the institute is INR 12 -14 LPA. However, this way of measurement is not an indicator of the quality of placements available on campus. The median salary is a better marker of the type of packages received by students. At IIIT A the median salary has been around INR 10-12 LPA.

2020 Placement Statistics: 

I hope this general placement data will give you an idea of what to expect for placements.
