In today's multicultural labour market, job applicants need to be ready for a job interview in English. These interviews are very competitive. Candidates need strong problem-solving skills and clear, confident communication. Even seasoned professionals can struggle when using English in this high-pressure situation.

Here are the top five mistakes we see candidates make—and how to avoid them!

1. Speaking too quietly or too fast

In some cultures, it’s normal to speak softly and quickly, especially in formal situations. But in a consulting interview in English, this can make it hard for the interviewer to understand you. To a Westerner, you may sound nervous or unsure, even if you’re not.

What to do:

Slow down and speak clearly. Practice pausing after key points. Focus on clarity, not speed.

2. Giving long answers without structure

Many candidates try to explain everything at once. They give long answers without a clear structure. This makes it hard for the interviewer to follow your logic.

What to do:

Use a simple structure like “First, second, finally” or the PREP method (Point, Reason, Example, Point). Take a moment to organise your thoughts before you speak.

3. Avoiding eye contact or showing little expression

Some business cultures value modesty and calmness. But in a Western interview, candidates are expected to show energy, confidence, and engagement. This lets the interviewer know that you are excited about the position.

What to do:

Make eye contact, smile, and show interest in the conversation. You don’t need to be loud—but do show that you’re confident and enthusiastic.

4. Not asking questions at the end

When the interviewer asks, “Do you have any questions for me?”, many candidates say “No.” But this is a chance to show your interest in the company and your communication skills.

What to do:

Prepare 2–3 thoughtful questions in advance. For example:

  • “What kind of training does your company offer for new consultants?”
  • “How do teams usually work together on a project?”

5. Trying to be perfect

Some candidates try to use very advanced English or avoid small grammar mistakes. This can slow you down and make you sound unnatural.

What to do:

Focus on being clear and confident. It’s okay to make small mistakes. The interviewer is looking for strong thinking and good communication, not perfect English.

Final tip

Practice with a partner or teacher before your interview. This will help you get comfortable speaking clearly and confidently. You’ll also get immediate feedback to improve.

Interviewing in a second language can be a challenge, but with the right preparation, you can perform at your best. Focus on clear communication, and be confident. With practice, your skills will keep improving and you'll get the job!
