My brother is currently studying at IIIT Lucknow and according to him, the current situation is not as good as it used to be earlier. 

Here is why:

• As IIIT Lucknow is a completely new institute and as per the laws of MHRD, it was run under the guidance of IIIT Allahabad. Earlier there wasn’t any difference between the students of IIIT Allahabad and IIIT Lucknow. Even the placements of about 19 LPA were made by labeling them as IIIT Allahabad students. 
• But in 2018, a case was filed against them to make IIIT Lucknow a separate entity. This resulted in the speedy construction of campus and the hiring of amateur professors.

• The campus wasn’t completely constructed and the students have shifted there anyhow. There were some rooms that substituted for classes, one hostel, one mess, that’s all. To this day, they don’t have proper lab facilities too. You will be given laptops which are to be returned later.
• Now coming to the placements, in 2019, IIIT L somehow managed to get average placement packages of 11 LPA. But for 2020, they weren’t able to call a single company. They also couldn’t get interns for the last year as well as this year’s batch. IIIT Allahabad, on the other hand, had an average package of 22 LPA and it is getting better every year.

At the end of the day, IIIT Lucknow is facing a crisis due to no experienced faculty, no placement/internships, and no alumni base. This is a matter of your entire career so do not fall bait to people from IIIT Lucknow stating that it's better than any IIIT. There is no comparison of IIIT Lucknow with IIIT Allahabad or any top NITs.
