Communication Skills for Interviews: 5 Skills and How to Improve

Most weak answers build up to the point. Strong answers open with it. This is the idea behind the pyramid principle from Barbara Minto, the McKinsey writing method consultants still learn: lead with the conclusion, then group your reasons under it.

• Weak: "So in my second year I joined a club, and there was this project, and we had some issues with the timeline..."
• Strong: "I turned around a late project by cutting its scope in half. Three things made that work."

Drill. Take five common questions. For each, write the first sentence only, and make it a full answer on its own. Then say it out loud.

Aim for about 60 to 90 seconds for most fit answers and up to 2 minutes for a full story. If you need longer, the story has too much setup.

• Use plain words. "We lost our biggest client" beats "we experienced significant client attrition."
• Use one number when it matters. "Sales fell 20%" is clearer than "sales fell a lot."
• Signpost. Say how many points you have and number them: "Two reasons. First... Second..." The interviewer can follow you and take notes.

For behavioral questions, the STAR method (Situation, Task, Action, Result) keeps you on track. Spend most of the time on what you did, and close with the result and what you learned.

Drill. Record one story. Play it back and cut every sentence that comes before the problem. Retell it in under 90 seconds.

Many candidates answer the question they prepared, not the one they heard. "Tell me about a time you failed" is not a request for a success story with a small setback.

• Pause for a second after the question. It shows you are thinking, not reciting.
• If a question is vague, ask one short clarifying question: "Do you mean in a team or on my own?"
• In a case, repeat the problem back in one sentence before you structure it. It catches a wrong assumption early.

Drill. Have a friend read you questions from our consulting behavioral list. After each answer, they say whether you answered what they asked. Practice the hard ones, like tell me about a time you failed and your biggest weakness.

Nerves make most people speak faster and fill gaps with "um," "like" and "you know." A short pause sounds more confident than a filler word.

• Slow down at the start of each answer. The first sentence sets the pace.
• When you lose your place, stop, breathe, and restate your last point.
• Do not try to remove every filler at once. Pick your most common one and replace it with a pause.

Drill. Answer three questions on video. Count your fillers per answer. Do it again the next day and aim for fewer.

You do not need power poses or scripted gestures. You need to look engaged and at ease.

• In person: sit upright, keep your hands visible, and look at the interviewer when you make your main point.
• On video: put the camera at eye level and look into the lens when you speak, not at your own picture. Light your face from the front, use a plain background, and close other apps.
• One-way video interviews (such as HireVue) have no live listener, so energy drops easily. Smile at the start and speak as if to one person. You can rehearse the format with our HireVue practice tool.

Drill. Record a two-minute answer and watch it once with the sound off. Note what you would change about your posture and eye line.

Hard or unexpected questions are a test of how you think, not of having a ready answer.

1. Buy a few seconds honestly. "Let me take a moment to think about that." Silence for five seconds is fine.
2. Clarify if anything is unclear.
3. Structure out loud. "I would look at this in two ways." Then go through each.
4. Give a view. End with a clear answer, even if you add a caveat.

A simple fallback is PREP: Point, Reason, Example, Point. State your view, say why, give one example, then restate the view.

• Finish your sentences. Trailing off makes a good point sound unsure.
• Put the key word at the end of the sentence, where the stress falls naturally.
• Avoid jargon the interviewer might not share. If you use an acronym, say it in full the first time.

• Prepare your opening. Knowing your first 30 seconds of walk me through your background takes the edge off the start.
• Breathe out slowly before you go in. A long exhale helps you settle.
• Treat a stumble as normal. Say "let me rephrase that" and keep going. Interviewers care about the recovery.
• Practice under pressure. Answering out loud to someone, or to an AI interviewer, is closer to the real thing than reading notes.

In consulting and banking, executive presence mostly means people can imagine putting you in front of a client. It comes from:

• Calm. You take a pause before answering and do not rush.
• Conviction. You give a clear view and can defend it.
• Brevity. You say what matters and stop.
• Listening. You respond to pushback instead of repeating yourself.

The last two minutes of a case interview are a communication test. Use the answer-first shape:

1. Recommendation: "The client should enter the market through a partnership."
2. Two or three reasons, each with the key number.
3. Risks and how to reduce them.
4. Next steps.

Say it as if the CEO has one minute. More on this in case interview preparation.

You can run the full mock with a friend, a coach, or out loud with Soreno. The point is to answer under some pressure and review what you heard.
