How to Answer 'What Is Your Biggest Weakness?' (UK Examples)

'What's your biggest weakness?' is one of the most dreaded UK interview questions — but it's also one of the easiest to prepare for. Interviewers aren't trying to catch you out; they want to see self-awareness and honesty. Here's how to answer it well, with examples.

Why interviewers ask it

They're checking three things: that you're self-aware, that you're honest rather than robotic, and that you actively work on improving. A polished non-answer like 'I just work too hard' signals the opposite — it sounds rehearsed and evasive.

The formula for a strong answer

• Name a genuine weakness that isn't a core requirement of the job.
• Show you're aware of its impact.
• Explain the concrete steps you're taking to improve.
• End on the progress you've already made.

Example answers

Weaknesses to avoid mentioning

• Anything that's core to the role (e.g. 'I miss deadlines' for a project manager).
• Fake weaknesses like 'I'm a perfectionist' or 'I care too much' — interviewers see straight through them.
• Red-flag personality traits such as 'I lose my temper'.
• Vague answers with no example and no improvement plan.

Quick tips

• Pick a weakness you've genuinely improved on, so you can show progress.
• Keep it to about a minute: name it, own it, show growth.
• Practise out loud so it sounds natural, not scripted.
