Ace the Interview

From the moment you sit down to the moment you walk out, every interview is a conversation you can prepare for. This guide breaks down the frameworks, questions, and habits that turn nerves into confidence.

Whether it’s a 7-minute speed date at the Sefa Company Fair or a final-round panel at a top employer, the fundamentals are the same: know yourself, know the company, and know how to tell your story.

1The STAR Method

Behavioural questions — the “Tell me about a time when…” ones — appear in almost every interview. STAR is the most widely-used framework to answer them clearly and convincingly.

S
Situation
≈ 20% of answer

Set the scene in 2–3 sentences. Just enough context.

T
Task
≈ 10% of answer

What was your specific responsibility or goal?

A
Action
≈ 60% of answer

The detailed steps you took. Use “I”, not “we”.

R
Result
≈ 10% of answer

The outcome — quantify wherever possible.

Worked example — “Tell me about a time you led a team under pressure”

S: During my second-year Marketing course, I was assigned to lead a five-person group project worth 40% of our grade. With three weeks until submission, two members dropped the course.

T: I needed to redistribute the workload, keep morale up, and still deliver a high-quality strategy report on time.

A: I called an urgent meeting, mapped every remaining task to a clear owner, and introduced two-day check-ins on Notion. I personally took over the consumer research section, conducted 12 short interviews in one weekend, and rebuilt the analysis.

R: We submitted on time and received a 9/10 — the highest in the cohort. Our professor used our framework as the example in the next year’s course.

💡

Pro tip: Build a “story bank” of 6–8 STAR examples before any interview. Each story should cover a different competency: leadership, conflict, failure, initiative, teamwork, analytical thinking, customer-focus, and learning agility.

2Know the Format You’re Walking Into

Screening / HR call

15–30 min, often by phone or video. Focus on motivation, basic fit, and availability.

3Questions You’ll Be Asked

Classics — prepare these, then rehearse until they sound natural

Tell me about yourself.
A 60–90 second arc: where you are now, one or two relevant experiences, why you’re sitting here today.
Why this company?
Show specific knowledge — a recent project, a value, a person you spoke to. Avoid generic praise.
What are your strengths and weaknesses?
Strengths: pick two, support each with a brief example. Weakness: real, not a humble-brag; show what you’re doing about it.
Where do you see yourself in five years?
Show ambition without boxing yourself in. Talk about the type of impact you want to have.

Behavioural — practice 2–3 STAR stories for each

  • Tell me about a time you led a team.
  • Describe a time you failed. What did you learn?
  • Tell me about a time you disagreed with someone.
  • Describe a situation where you had to meet a tight deadline.
  • Tell me about a time you took initiative without being asked.
  • Tell me about a time you received difficult feedback.

4Questions You Should Ask

Growth & learning
  • “What does success look like after six months?”
  • “How does the team support learning?”
  • “What are typical career paths from this role?”
The work itself
  • “What does a typical week look like?”
  • “What are the most interesting projects right now?”
  • “What’s the hardest part not obvious from outside?”
Team & culture
  • “How would you describe the team’s working style?”
  • “How does the team give and receive feedback?”
  • “What has the team changed or improved recently?”
The interviewer
  • “What made you join, and what’s kept you here?”
  • “What’s surprised you most about working here?”
  • “What advice would you give someone in my position?”

5The Preparation Timeline

One week beforeRead the job description twice and underline the five most important keywords. Map a STAR story to each.

Five days beforeResearch the company: latest annual report, three recent news items, the team you’d join, and one or two people on LinkedIn.

Three days beforeRun a mock interview with a friend or record yourself answering five questions aloud. Watch it back — most people speak faster than they think.

The day beforeConfirm location, route, and timing. Lay out your outfit. Re-read your CV — make sure you can speak to every bullet.

The morning ofEat properly. Arrive 10 minutes early — not earlier, not later. Smile at reception; they sometimes pass on impressions.

Within 24 hours afterSend a short thank-you message referencing one specific thing from the conversation. Update your tracker with next steps.

6On the Day

First impressions

Firm handshake, eye contact, smile. Wait to be invited to sit. Match the formality the interviewer sets.

During answers

Pause briefly before answering — it shows you’re thinking, not panicking. It’s fine to say “let me think for a moment”.

If you don’t know

Honesty beats bluffing. Walk through how you’d approach finding the answer. Interviewers test reasoning more than recall.

7After the Interview

“Thank you for taking the time to walk me through your team’s work yesterday. Your point about how the team prototypes campaigns in 48-hour sprints really stuck with me — that pace and proximity to real consumer reactions is exactly the environment I want to learn in. I’m even more excited about the role and look forward to hearing about next steps.”

Reflect — even if you don’t get the role

  • What three questions caught you off guard? Add STAR answers to your story bank.
  • What three questions did you answer well? Note what made them work.
  • If rejected, ask for feedback politely — many companies will share it, and it compounds across applications.

🎯

Remember: Interviews are a two-way conversation. You’re also deciding whether they are right for you. The candidates who get offers are usually the ones who treat the interview as an authentic exchange, not a performance.
