The key consulting interview skill Don't rush to the answer. Start with structure.

For example

“I'd break this into three areas: market demand, economics and competitive response.” Now the interviewer can follow your thinking. Practice case interviews out loud Writing a case solution isn't enough.

A real case requires you to

listen → structure → ask → calculate → interpret → communicate Practice that sequence. A useful mock case format Minute 0–3: Understand the problem Minute 3–8: Build structure Minute 8–15: Analyze Minute 15–20: Synthesize Minute 20–25: Recommendation

Then practice the follow-up

“What would change your recommendation?” That's where your reasoning gets tested. [Run a consulting mock interview with Mockly]
