Hello,

If you got an interview call from IIT BHU and you were not able to attend the interview on the selected date then no need to worry. You should contact the authorities of the institution as soon as possible and tell them that you belong to state where recently a natural calamity took place. Then depending on the condition the incharge will ask you for the next date on which you can give your interview. But make sure that next time you should positively appear for your interview.
