I did ‘ok’ in the first round and was not tested on quants. Also had in my feedback that my structure was shaky.
Had a second round today and made a math mistake (a 0 and a hickup in the equation that I fixed myself) and missed an important branch of the strucure. Infuritating as the calculations were really not hard. The fit however seemed very genuine and it was a real collaborative interview overall (fit and case).
I know we can't quantify my chances but if anyone ex-BCG or experienced with interviews at BCG could give me an idea that would be amazing :)
