Excel Interview Prep with Excel Practice: 30-Minute Daily Plan

By ZonoTools6 min read

What interviewers usually test

Most Excel interview rounds check three things:
- Can you select the right formula quickly?
- Can you avoid logic mistakes under pressure?
- Can you explain your formula clearly?

Practice should target all three, not just syntax memorization.

30-minute daily prep routine

  • 10 minutes: core formulas (IF, SUMIFS, COUNTIFS).
  • 10 minutes: lookup scenarios (XLOOKUP, INDEX + MATCH).
  • 10 minutes: explain one solution in plain language.

Explaining your logic helps you perform better in live interviews.

High-frequency interview formula set

  • IF, IFS, IFERROR
  • SUMIF, SUMIFS, COUNTIF, COUNTIFS
  • XLOOKUP, VLOOKUP, INDEX + MATCH
  • TEXT, DATE, EOMONTH

Covering this set gives strong baseline coverage for analyst and ops roles.

How to self-evaluate each day

  • Did your first attempt return the expected result?
  • Did you use the minimal clear formula?
  • Could you explain each argument without hesitation?

Keep a short log. Small daily improvements compound fast.
