Expert Tips

  • Research the company's mission, recent news, and products/services before the interview — it shows genuine interest.
  • Practice your "tell me about yourself" answer until it sounds natural, not rehearsed.
  • For aptitude tests, practice under timed conditions — speed and accuracy both matter.
  • Prepare 3–5 STAR stories that can be adapted to different behavioral questions.
  • Send a thank-you email within 24 hours of the interview — many candidates skip this and it makes a difference.
