Mastering the Interview: 'What is your biggest achievement?'

Job interviews can be nerve-wracking, especially when English is your second language. One of the most common and critical questions hiring managers ask is: "What is your biggest achievement?"

Your response to this question can set the tone for the rest of the interview. Employers are not just evaluating your answer; they are evaluating your English fluency, confidence, and ability to structure your thoughts.

The Best Approach

When answering "What is your biggest achievement", avoid giving vague or overly rehearsed answers. Use the STAR method (Situation, Task, Action, Result) to structure your response if it's behavioral. If it's a general question, keep your answer concise, professional, and relevant to the job description.

Useful English Phrases

  • "In my previous experience..."
  • "I successfully managed to..."
  • "My primary focus has always been..."
  • "I am particularly proud of..."
