Hey,

Generally, after the DUET entrance exam for admission into the Masters in Operational Research and other similar courses, candidates who qualify and meet the required cutoff are called for the interview process.

Last year, the interview got cancelled due to the Covid 19 pandemic. This year if the situation seems to be conducive by the authorities, they may conduct interview process as it is a part of the selection process. However, it will all depend upon the authorities but you need to keep yourself prepared for the best.
