For a standard 30 minute case interview, I've heard that you should take ~2-3 minutes to write down a framework and 3 minutes to explain it.
However, for first round interviews with 20 minute cases, this combined with the opening could be almost half the case.
How should I determine how long I can take on a framework and are there any opening questions I can ask the interviewer to get a better idea about the framework time for this individual case?
