Is it ok to ask the interviewer "does that sound right" after doing your math calculations to see if you got the right numbers? Some interviewers give no verbal cues on whether you are on the right track, so can I ask this?
Hi there,
If you want to check if the approach is right (not only for math but in general), I would avoid to use the “Does it sound right?” statement. It will give the impression you are not confident.
I would use an indirect approach instead. A possible way is to say “If that’s fine with you, I would move now to the next area, XYZ”. This will give the option for the interviewer to interrupt you if you have done mistakes and ask if you are sure about the math.
It is also good practice to do a double check on the numbers after you got the math result.
As bonus tip: never start the math doing the math (I know it is counterintuitive ;)). You should start presenting the structure for the math, then when you get approval from the interview, add the numbers. This will create an additional opportunity for the interviewer to confirm that the approach is correct.
Best,
Francesco
Hi there,
I agree with the other coaches here - this is something you want to avoid if possible.
Rather, learn to sense check your numbers (i.e. check magnitudes) and practice fast math to minimize mistakes.
This one could be quite subjective but I personally would discourage from "checking the answer" with your interviewer. The interviewer is not only looking for your ability to develop an approach, run the calculations and distill the insights but also your comfort in independent quantiative thinking. In other words, can I put this candidate in front of my client.
Its okay as long as you do it cautiously. If you over do it, its game over. Its should be more of tell & validate rather than ask.
Before asking, just spend some extra seconds to sense check your answer and provide explanation/evidence/assumptions.
