All the three BITS campuses follow the same curriculum, and the faculties are equally good at each of them. Moreover, all of them have a good infrastructure. All three of them provide excellent learning and development opportunities to students, and the peer groups at each of them are quite good.
The slight difference is that some influential firms only make recruitments from the Pilani campus. But many MNCs choose to recruit students from all three BITS campuses. On campus recruitments do not define the entire career path of any individual.
Some of my seniors at BITS performed really well in UPSC, some went on to pursue their MS, and others rose to high management positions through sheer hard work that they learned during those four years at BITS. The only drawback is that the fees are much higher compared to the NITs.
BITS Hyderabad is an excellent choice for your engineering studies. But everything ultimately depends on your dedication and hardwork.
