What kind of questions are asked in the Integrated PhD interview for Physics at IISc, TIFR, and HRI?

IISc Bangalore, TIFR, and HRI conduct interviews for the integrated Ph.D in Physics. My brother appeared for the TIFR NCBS Bangalore interview for iPh.D. in Physics. 

People from different backgrounds appear for the NCBS interviews in various disciplines. 

NCBS has Rounds 1 and 2 for the interviews. Round 1 lasts for 30-40 minutes. Here a candidate’s basics are tested. Round 2 lasts for 75 minutes. It involves more detailed questions which are usually based on the projects or write-ups done by a candidate. 

For my brother, however, the interview went the other way around. During the first round, he was asked questions about his projects. During Round 2, he was asked detailed questions in the broad areas of Physics and Maths. 

The interview experience for each candidate will be unique, whether in IISc Bangalore, TIFR, or HRI. This is especially true for NCBS as their research is not just limited to Physics, it is interdisciplinary. The interviews will help you learn something new. Prepare well for them and enjoy the process.
