Hello,
I recently had a case interview and was struggling on the math. The interviewer and I agreed on the numbers until the second to last step, where let's say I kept getting the final answer as 7050. After struggling for a while, the interviewer told me the answer was 7500. We then ran out of time. Going through the steps again, I am almost certain that his answer key had wrongly written the answer as 7500 instead of 7050, especially since we aligned on everything up to the second to last step which only included some simple arithmetic. However, he was a partner so I assume he was familiar with the case/may have given it before (unsure). Is there anything I can do about this/what should I do?
