Hi,
It's really hard to say without knowing the context. But if the interviewer said you lack the ability to COME to the point, it could have meant several things:
1) You lack the ability to dig deep enough to find the root cause and you switch too fast to the other parts of your framework. For example, if after the calculations you find out that the product mix has changed, you say out loud something like this: "We found a problem - our revenues has declined because the product mix has changed. I see several solutions how to fix this problem"
In reality, you still don't know the root cause - what has led to a change in the product mix? Was it a shift in the customer demand? Or maybe there is something going on with our sales department? You always have to find the root cause first and only after that generate the recommendations.
2) You are not straight to the point in your questions. For example instead of asking: "Could you please tell me what is the market size and the growth rate?" you ask something like "Do we know how is the market doing?". In other words, your questions are not asking for something specific and are too broad. Several questions like this in a row may be irritating for the interviewer since it's becoming extremely hard for him to give you the case.
