How is IIIT Lucknow?

This answer would be exclusively based on how IIIT Lucknow is doing currently. To start with this, let us first understand what all factors together comprise to make any college a good college.

These include the following - 

• Curriculum- The entire curriculum that IIIT Lucknow offers is two separate courses. These are B.Tech in CS and B.Tech in IT. This sort of course structure is apt for anyone keen to pursue their career in the technology field. 
• Faculty- All the professors teaching at IIIT Lucknow are Ph.D. holders. But what you need to realize is that the faculty would not pay much heed to your skills and progress. 
• College life- IIIT Lucknow may not be able to fulfill that desire of yours to be exposed to aspects like sports, dance, drama, business, music, qualities of a budding entrepreneur, etc. Their sports ground isn't as big as other IIITs have. You would have two badminton courts, two tables for table-tennis, two carrom-boards, etc.
• Placements- Perhaps the most false claims about placements are made by IIIT Lucknow. All of IIIT Lucknow's placement credit goes to IIIT Allahabad. 

• Internships- No student was able to grab an on-campus internship for them in 3rd-year at IIIT Lucknow. And this is simply because of a flawed system and no lab facilities. No one in my knowledge had an on-campus internship and this doesn't happen in general.
• Fest- Lately, a technical fest was conducted by IIIT Lucknow. The students were happy and all excited but there are always bigger and better fests in other institutes. IIIT Lucknow is planning to execute a cultural fest, but accommodating the number of colleges will be a problem, as it is not spacious enough.

In case you're looking to join IIIT Lucknow in 2020-21, make sure you check out some Google images of hostels. The number of hostels is less. They have just one hostel that is cluttered with all the students from each year, including Ph.D. and M.Tech students.
