Had a case interview in tier 2 consulting firm,
The case case about: You are a director of quality assurance department of pharm company. They have a new drug, which were sold within a year and everything was ok. But last month 50 people reported that they had a minor allergy to it, like skin irretation. So should he recall all batches.
In total they sold over 700k of this drugs throughout a year.
I didnt know what other questions to ask, so my anwer was: They shouldn't recall all batches because 50 out of 700k is so small number, and most likely thos 50 people were their own problems which is not related to our drug.
But my interviwer told me, i was wrong, that they should have recalled all batches even if it's 1 reported/confirmed case there.
Was my logic right here? I dont agree with interviwer
