Many interviews include a question about your biggest success. One common example is “What is your greatest achievement?” Sample answers are on their way!
Employers ask this question because it reveals more than just your job title or a list of responsibilities. Answer this question well, and you show interviewers how you approach problems and what results you achieved.
It’s not unusual for candidates to worry that their achievements are not impressive enough – but in reality, interviewers usually look for examples that show initiative, improvement, and clear outcomes rather than dramatic accomplishments.
It’s similar to how the “What are your weaknesses?” interview question looks to draw reflections on your professional growth.
On paper, many candidates look similar. Achievements help interviewers understand what you actually did and the results you created.
A clear example shows how you approach problems and how you contribute to results. Interviewers also learn what you consider important in your work.
Achievements give real proof of what you can do. Anyone can describe themselves as organised or hard-working, but a real example shows those qualities in action.
For employers, this question helps answer a simple question: What difference did this candidate make in their previous role?
Note: we discuss other common interview questions, like your greatest achievement, on our blog.
Always remember that if a company has offered you an interview, that’s already a great step forward! Employers only interview about 6 candidates on average, the UK Careers Fair reports.
The right example makes this question much easier. Your best achievement should demonstrate a skill that matters for the role you are applying for.
Think about moments where something improved because of your work. That improvement might involve performance, efficiency, customer satisfaction, or teamwork.
Common examples include:
Numbers can make achievements more convincing, but they are not essential. Even small improvements can show initiative if you explain them clearly.
Many candidates overlook everyday successes. Introducing a better way to organise work or helping a project run more smoothly can still be a strong interview example.
It can be easy to lose clarity or veer off course when describing an achievement. By using a simple structure, you can explain your example without drifting into unnecessary detail.
A widely used approach when answering a competency-based interview question is the STAR method. PurpleCV has a guide explaining the STAR method for interviews, but the idea itself is straightforward.
STAR stands for:
This structure helps interviewers understand your role in the situation. It also keeps your answer concise and focused.
When using the STAR method, focus most of your explanation on the action and the result. Those parts show how you think and what impact you created.
Preparing examples before your interview will make answering this question much easier. The examples below show how a what is your greatest achievement sample answer might sound in practice.
In my previous sales role, our team struggled to convert enquiries into confirmed clients. Many leads stopped responding after the first conversation.
I introduced a simple follow-up process and created a shared spreadsheet so the team could track each lead. Over the next few months, the team improved conversions and exceeded its monthly sales target.
During my final year at university, my group worked on a research project with a strict deadline. Early on, the team had difficulty organising tasks and managing progress.
I suggested creating a timeline and dividing the work into clear responsibilities for each member. The structure helped the group stay organised and the project received one of the highest marks in the class.
While working in customer service, I noticed that many enquiries involved order tracking. Customers often contacted support because they could not easily see delivery updates.
I worked with colleagues to improve how tracking information appeared in confirmation emails. The change reduced the number of customer enquiries about order updates.
Focus on the results of your actions rather than describing your daily responsibilities. Interviewers want to understand what changed because of your work.
Choose an example that relates to the role you are applying for. A relevant achievement helps employers see how your experience fits their needs.
Keep your answer concise and structured. Most responses work best when they take around one or two minutes.
Preparation also helps. Thinking about your achievements before the interview makes it easier to explain them clearly when the question appears.
It can also help to highlight similar successes when writing achievements on your CV rather than listing responsibilities alone.
Of course, seeking additional support can be a real confidence boost. Our tailored interview coaching services provide the chance to work alongside a careers professional to perfect your interview technique – and calm your nerves.
Some candidates talk about team success without explaining their own contribution, but employers still want to understand what you personally did. Don’t diminish the importance of your own role.
We often hear candidates describe their responsibilities as opposed to honing in on a specific achievement. Responsibilities show a hiring manager what your job involved, while achievements show the results you created. Keep this distinction in mind.
Another common mistake involves choosing an example that has little relevance to the role. Selecting an achievement that demonstrates useful skills makes your answer much stronger. This goes to show the importance of carrying out sufficient pre-interview prep.
A strong answer describes a real situation where your actions led to a positive result. The story should explain the challenge, what you did, and what changed afterwards.
Achievements generally involve improving something. This could include increasing performance, solving a problem, or helping a team complete an important task. Employers mainly want to see how you think and how you contribute to results.
You can use achievements outside work as examples in interviews as long as they demonstrate relevant skills. These might include university projects, volunteering roles, or leadership activities. This approach can work particularly well if you’re a graduate or early in your career.
Many candidates early in their careers have limited work experience. Academic projects, internships and part-time roles can still provide useful examples. Focus on situations where you solved a problem, improved something, or helped a group achieve a goal.
