Since each candidate would be called at forty minute intervals starting from 11.00 am on 26th February 2023 at the Tata Hall in the IIM Calcutta campus, the timings of the start of the eight interviews would be 11.00 am, 11.40 am, 12.20 pm, 1.00 pm, 1.40 pm, 2.20 pm, 3.00 pm and 3.40 pm.

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 Subir was an accountant who was called at 3.00 pm, 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. Quereshi   Mr.Partha Mr. Subir  
Profession     Engineer     Accountant Accountant  
Percentile     98.35 98.87        

Dr Ratan (MBBS) was called after 2.20 pm (d). The only slot vacant after 2.20 pm was 3.40 pm. So Dr Ratan (MBBS) was called at 3.40 pm.

Neither the first nor the last interviewee was an engineer (e). Yet there were four engineers who were called for the interview. So the slots at 11.40 am, 1.00 pm and 1.40 pm were definitely engineers. Hence the English professor Mr Williams was called at 11.00 am, as that was the only slot left. Also Mr Tanmoy, Mr Umesh and Mr Vittal were engineers.

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. Quereshi   Mr.Partha Mr. Subir Dr Ratan
Profession Professor Engineer Engineer Engineer Engineer Accountant Accountant Gen Prac
Percentile 99.97   98.35 98.87        

From the above we can definitely conclude that :

Mr Partha was called after Mr Vittal.

Mr William was called at 11.00 am

Dr Ratan (MBBS) was called at 3.40 pm

Mr Umesh was called at either 11.40 am or 1.40 pm

Hence, Mr Umesh was called at 1.40 pm may not be definitely correct.
