A relative of mine used to be a student of IIIT Vadodara and he is all praise for the institute. The college has improved a lot over the years and is still improving.
The coding culture of the institute is evolving by the day. The seniors as well as the faculty will enthusiastically support you. The institute is still undergoing development and may not be able to stand toe to toe with other elite institutes but the students are hopeful that someday it will.
Major companies that have participated in the placement drive are Adobe, CodeNation, DirectL, etc. Some students also ended up bagging internships during the summer break. The internships were offered by Mathworks, Amazon, Quikr, etc.
Another big names that have offered placements are PayTm. KPGM has offered placements off-campus. A few students have also interned for companies in Germany, France, and Japan.
The institute has been gaining repute and things are looking good and they will no doubt get better. My relative has no regrets whatsoever when he graduated from this IIIT Vadodara.
