What the Success Profiles framework actually assesses
UK Civil Service recruitment uses the Success Profiles framework, which can assess up to five elements depending on the role: behaviours, strengths, ability, experience, and technical skills, moving beyond the older competency-only model. Behaviours (such as making effective decisions, communicating and influencing, and delivering at pace) are assessed through structured, STAR-style questions, while strengths-based questions ask about what you naturally enjoy and do well, assessed differently and often with less advance preparation possible.
How behaviours and strengths questions differ
Behaviour questions ask for a specific past example demonstrating a named behaviour, and benefit from careful STAR-format preparation in advance, similar to standard competency questions. Strengths questions ask more spontaneous, in-the-moment questions about what energises you or what you do well, deliberately designed to be harder to over-rehearse, so genuine, quick, honest reflection tends to work better than an overly polished, prepared-sounding answer.
How to prepare
Check the specific job advert and person specification carefully, since it will list exactly which behaviours are being assessed for that particular role, and prepare a clear STAR example for each one listed. For strengths-based questions, reflect honestly in advance on what kinds of tasks genuinely energise you and where you feel most naturally effective, rather than trying to prepare a scripted answer.
