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,IFERRORSUMIF,SUMIFS,COUNTIF,COUNTIFSXLOOKUP,VLOOKUP,INDEX + MATCHTEXT,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.
