Had a R1 with BCG for a SA position. I was interviewing with a Partner. Client was a cement manf. seeing a $300 increase in EBITDA / ton.

It was a profitability case. I began well and asked for all scoping questions correctly. It was evident that cost side was the issue and I drew out the value chain and started investigating one by one different parts of the VC.

I went through the VC but was not able to identify the cost driver issue. At the end - the interviewer told me that within Raw Materials I only enquired about the Price of raw material and did not ask about the quantity and in reality - the quantity of Raw Mat had increased.

I realised I made this mistake. Do you think there will be an R2 or is this it? I am interviewing laterally.

The partner later asked me some questions which I was able to answer correctly. He also mentioned at the end "Hope to see you join soon". I feel he was just being nice and I've done terribly.

Need some perspective here.
