Strengths-based interviews were introduced partly as a reaction to competency-based interviewing. The concern with competency interviews is that highly prepared candidates can give polished, coached answers that don't reflect how they actually think and work. Strengths-based questions are designed to surface genuine enthusiasm and natural aptitude — things that are harder to fake.
What strengths-based interviews are
Rather than asking "tell me about a time you did X," strengths-based interviews ask questions like "what do you enjoy most?", "what comes naturally to you?", or "when do you feel most energised at work?" They're trying to understand what you're actually good at and whether those things align with what the role needs.
The theory is that people are more effective and more engaged doing things that feel natural to them. Employers want candidates who will genuinely thrive in the role, not just technically be able to do the job.
Common among: large graduate recruiters, banks, professional services firms, and tech companies that have moved away from pure competency frameworks. Unilever, PwC, EY, and Nestlé have all been known to use strengths-based approaches.
How they differ from competency interviews
Competency interviews want evidence. Strengths interviews want authenticity. The signals assessors look for are different:
- Do you light up when you talk about certain topics? (Signs of genuine strength)
- Does your energy drop when asked about something? (Signs that it may be a weakness, even if you can do it)
- Do you answer spontaneously, or does your answer feel rehearsed?
- Do you use "I" naturally, or does it sound like you're performing an answer you memorised?
Because of this, over-rehearsing can actually hurt your performance in a strengths interview. Assessors are trained to spot scripted answers.
Common strengths-based questions
About enjoyment and energy:
- "What do you enjoy most about your current or most recent role?"
- "When do you feel most energised at work?"
- "What kind of tasks do you find yourself doing even when you don't have to?"
About natural abilities:
- "What do you find easy that others seem to find hard?"
- "What would your friends say you're really good at?"
- "What kind of problems do you naturally gravitate towards solving?"
About learning and growth:
- "What have you learned recently that you got into because you wanted to, not because you had to?"
- "What skill are you working on developing right now?"
About challenge and discomfort:
- "Tell me about something you find genuinely difficult."
- "What kind of work drains your energy?"
How to prepare without over-rehearsing
Self-reflect rather than script. Before the interview, genuinely think through what you find energising and what drains you. Not what sounds good — what's true. The best preparation is honest introspection, not polished stories.
Match your strengths to the role. Look at the job description and identify which of your genuine strengths overlap with what the role needs. These are the strengths you should naturally surface. Don't manufacture strengths you don't have — it shows.
Have brief examples ready. When you name a strength, be ready to illustrate it with a brief, natural example. Not a polished STAR answer — just a sentence or two that makes it concrete. "I find analytical work energising — I'd often spend extra time on data problems in my last role even when it wasn't strictly required."
Be honest about weaknesses. Assessors specifically ask about drains and difficulties to test authenticity. Candidates who claim they have no weaknesses or that everything energises them score poorly. A genuine answer to "what do you find difficult?" is far more impressive than a diplomatic non-answer.
