Job Interview Preparation Guide

Master behavioural interviews, competency questions, and technical screenings. Learn the STAR method and common interview mistakes to avoid.

Job interviews can be nerve-wracking, but thorough preparation is the best antidote. This guide covers everything from research to follow-up.

1. Research the company thoroughly

Before any interview, you should know:

  • Mission and values — What does the company stand for?
  • Recent news — Any launches, acquisitions, or changes?
  • Products/services — What do they sell or offer?
  • Competitors — Who are they up against?
  • Culture — Check Glassdoor, LinkedIn, and their careers page

2. Master the STAR method

Most behavioural questions can be answered using STAR:

  • Situation — Set the scene briefly
  • Task — What was your responsibility?
  • Action — What did YOU do? (This is the longest part)
  • Result — What happened? Quantify if possible

Pro tip: Prepare 5-7 STAR stories that can be adapted for different questions. Practice them until they flow naturally.

3. Common interview questions

Be ready for these classics:

  • "Tell me about yourself" — Keep it to 2 minutes, focus on relevant experience
  • "Why do you want this job?" — Connect your goals to the role
  • "What's your greatest weakness?" — Be honest but show self-awareness
  • "Tell me about a time you failed" — Focus on what you learned
  • "Where do you see yourself in 5 years?" — Show ambition aligned with the company
  • "Why are you leaving your current job?" — Stay positive, focus on growth

4. Body language matters

  • Maintain eye contact (but don't stare)
  • Sit up straight with open posture
  • Use natural hand gestures
  • Smile when appropriate
  • Nod to show you're listening
  • Avoid fidgeting, touching your face, or crossing arms

5. Questions to ask the interviewer

Always have questions ready:

  • "What does success look like in this role after 90 days?"
  • "What are the biggest challenges the team is facing?"
  • "How would you describe the team culture?"
  • "What's your favourite part about working here?"
  • "What are the next steps in the process?"

6. After the interview

  • Send a thank-you email within 24 hours
  • Reference something specific from the conversation
  • Reiterate your interest and fit
  • Keep it brief — 3-4 sentences is enough
