Mental Math Phone Screen Prep
Mental math phone screen prep for explaining arithmetic clearly in verbal or remote quant technical screens.
Candidates preparing for verbal arithmetic and remote technical screens.
Make arithmetic audible
In a phone screen, the interviewer cannot see your scratch work. Say the calculation path clearly enough that they can follow the setup and correction.
Keep decompositions short
Use simple chunks like 10 percent plus 5 percent, or round then correct. Long mental detours are hard to follow verbally.
Concrete pattern
Say: "I will compute 18 percent as 20 percent minus 2 percent." Then calculate the two parts and give the final number with a quick reasonableness check.
Correct cleanly
If a number sounds off, say you want to check it. A clear correction is usually better than continuing with a hidden mistake.
Common mistakes
Candidates often go silent during arithmetic. In verbal screens, a compact explanation is part of the answer because the interviewer cannot inspect scratch work.
Practice the pattern
Use the LeetQuidity curriculum and calibration to turn this topic into a focused practice plan.
