What Is Your Greatest Accomplishment? Interview Question (2024)

“What is your greatest accomplishment?” is one of the most challenging behavioral questions you can be asked during a job interview.

As children, we are often taught to practice humility; to not show off in social situations because it is considered rude. Consequently, as adults, we often feel awkward discussing our greatest achievements, even if we are asked about them directly. We subconsciously worry we are coming across as unlikeable or obnoxious.

Of course, in many situations, including at work, humility is a useful trait. But the entire purpose of a job interview is to convince your interviewer that you are the best person for the job. So, start embracing what makes you great.

This article will outline the purpose of behavioral interview questions and help you understand what your interviewer is really looking for when they ask about your major accomplishment, It will then explain how to prepare your answer and provide some sample answers to help you get started.

Why Interviewers Ask “What Accomplishments Are You Most Proud Of?”

Contrary to what your subconscious is trying to tell you, your interviewer isn't attempting to trick you into revealing arrogance when they ask the ‘greatest achievement’ job interview question. They just want to know what it is that makes you stand out from the crowd.

As with all behavioral interview questions, it is crucial that you practice in advance.

The best way to describe your greatest achievement while only including relevant information is to use the STAR interview method. The acronym works as follows:

• S = Situation. In what context did your greatest accomplishment occur?
• T = Task. What challenges did you face or what goal did you want to achieve?
• A = Action. What action did you take? What skills did you use?
• R = Result. What was the result? What did you learn from the experience? Why is this your greatest accomplishment?

Ideally, you should talk about a workplace accomplishment. However, you could refer to school, volunteering or even your hobbies, so long as you demonstrate transferable skills and prove you are the best person for the job.

‘My greatest achievement’ examples could include:

• Giving a great presentation at work.
• Beating sales targets.
• Training for and completing a marathon.
• Organizing a successful charity event.
• Mentoring a coworker or fellow student.

Now you know how to structure your answer and the common pitfalls to avoid, here are some examples of accomplishments using the STAR technique to help you prepare your own.

Your answer should be clear and detailed. Avoid using vague language such as, “I oversaw a project.” Explain what the project entailed and what your role in it was.

Typical Mistakes to Avoid

Steer clear of any of these:

• Rambling – A long-winded answer will indicate to your interviewer that you are unprepared. Using the STAR interview method to ensure you are only mentioning the key points is an easy way to avoid this problem.

• Indecisiveness – Don’t give your interviewer a long list of possible achievements because you cannot decide which one to discuss. Prepare your answer in advance, so you don't have to think up an accomplishment on the spot.

• Trying to be funny – For example: “My greatest achievement was when I managed to get to work on time for once. Just kidding, my real greatest achievement is…”

  There can be a time and a place for humour in a job interview, but it is not when the interviewer has asked you a serious question.

• Putting others down to make yourself look better – Do not fixate on others’ failures or use them to make your accomplishment seem more impressive, even if your accomplishment involves you correcting someone else’s mistake.

  For example: “One time, a coworker completely messed up and deleted loads of files. He tried to recover them but he was never very good at his job so, needless to say, he was unsuccessful. In the end, I felt obligated to step in. Of course, I succeeded where he failed.”

  Other people’s shortcomings may be incidental to your story, but focusing on them will make you appear unprofessional or suggest that you are insecure. Focus on your own qualities instead.

Examples of Bad Answers

“What’s my greatest achievement? I’m not sure.

"Maybe the time I stopped two coworkers arguing? Is that an accomplishment?

"One time I gave a great presentation at work... Or once, I raised £600 for a sponsored run, but I guess it wasn't a great accomplishment because I gave up in the middle and had to return the money to my sponsors.”

Why this answer is bad:

• The candidate has vocally expressed indecisiveness, which is not an attractive trait in a potential employee.

• They rambled but failed to expand on any of their accomplishments or talk about their skills.

• They ask the interviewer for reassurance, indicating they have low confidence.

• They mentioned an accomplishment but then reduced its impact by expressing doubt about its worth.

“My greatest accomplishment is finally passing my driving test. I actually failed four times and passed on my fifth attempt.

"The first time I failed was because I was speeding. The other times weren’t my fault. I was so happy when I finally passed. I’m a great driver.”

Why this answer is bad:

• The situation is irrelevant in a work context.

• The answer does not specify any key skills or values which would make them a great job candidate.

• The candidate focuses on their failures rather than their successes.

• The candidate disparages others in an attempt to make their achievement appear more impressive.
