The interview panel at IIM Calcutta decided to interview eight candidates – Mr Partha, Mr Quereshi, Dr Ratan (MBBS), Mr Subir, Mr Tanmoy, Mr Umesh, Mr Vittal and Mr William, on the 24th January 2023.

Tabulating the originally given data given would yield the following :

Time 11.00 am 11.40 am 12.20 pm 1.00 pm 1.40 pm 2.20 pm 3.00 pm 3.40 pm
Name       Mr. Quereshi   Mr.Partha    
Profession     Engineer     Accountant    
Percentile     98.35 98.87        

Now, if Mr Vittal, an accountant with a percentile of 99.87, was called at 11.40 am, then :

Time 11.00 am 11.40 am 12.20 pm 1.00 pm 1.40 pm 2.20 pm 3.00 pm 3.40 pm
Name   Mr. Vittal   Mr. Quereshi   Mr.Partha    
Profession   Accountant Engineer     Accountant    
Percentile   99.87 98.35 98.87        

Neither the first nor the last interviewee was an engineer (e). Hence the candidates who were called at 1.00 pm, 1.40 pm and 3.00 pm were engineers. Hence the candidates who were called at 11.00 am and 3.40 pm were the remaining English professor and the general practitioner, in any order. But Dr Ratan (MBBS) was called after 2.20 pm (d). Hence Dr Ratan (MBBS) was called at 3.40 pm. Thus the English professor Mr Williams was called at the other remaining slot of 11.00 am.

Thus :

Time 11.00 am 11.40 am 12.20 pm 1.00 pm 1.40 pm 2.20 pm 3.00 pm 3.40 pm
Name Mr.William Mr. Vittal   Mr. Quereshi   Mr.Partha    
Profession Professor Accountant Engineer Engineer Engineer Accountant Engineer Gen Prac
Percentile 99.97 99.87 98.35 98.87        

From the above we can definitely conclude that :

Dr Ratan was called at 3.40 pm 

Mr William was called at 11.00 am

Mr Umesh was called at either 1.40 pm or 3.00 pm

Mr Quereshi was an engineer

Hence, Mr Quereshi was an engineer is the only option that is definitely correct.
