I would rather see clean written arithmetic than a fast mental mistake, imo.

I can do most calculations mentally, but under pressure I am more accurate if I write down intermediate steps. Does writing out simple multiplication or division make me look weak, or is accuracy more important than doing everything in my head?

Sometimes under pressure I freeze on a calculation I would normally do instantly. If that happens on something basic like 7 x 8 or 12 x 6, what is the best way to recover without making the moment feel bigger than it is?
Mayank G.CoachTreat the blank as a small calculation issue, not a crisis. Pause, break the multiplication into easier pieces, and keep your explanation calm.
I can usually get the math right, but when I explain every step out loud I sound slow and mechanical. How much of the calculation should I actually verbalize in a case interview?
Mayank G.CoachVerbalize the setup and the important intermediate logic, not every tiny arithmetic operation. The interviewer needs to follow your reasoning, but they do not need a play-by-play of basic multiplication.
Sometimes an exact calculation would take time, but a quick estimate seems enough to make the decision. How do I know when approximation is acceptable, and how much error is reasonable before the estimate becomes misleading?
Mayank G.CoachApproximation is acceptable when the case needs direction rather than precision, but you should make the level of accuracy explicit. The estimate must still be good enough to support the decision.
