7 Mistakes International Candidates Make in UK Job Interviews

You’ve got an interview with a UK company. Congratulations! Your CV has already done its job: the company believes you have the skills they need.

So what is the interview really for? In the UK, interviewers are quietly asking themselves some hidden questions about you. Will I enjoy working with this person? Do they really want this job?

In this post, I’ll share seven mistakes I often see international candidates make. For each one, I’ll explain the hidden question the interviewer is asking, and what you can say instead.

If you’d prefer to watch, this post is based on my YouTube video, 7 Mistakes International Candidates Make in UK Job Interviews.

The hidden question: Will I enjoy working with you?

Interviewers can only answer this if they get a sense of your personality. In the UK, the interview starts before the formal questions. It starts when you meet the receptionist or walk into the room with the interviewer. Relationships matter here, so small talk matters too.

A common mistake is giving a very short answer to a small talk question. Imagine the interviewer asks, “Did you find us OK?” (meaning: did you find the building easily?). If you just say “Yes, thank you,” it’s polite, but the conversation stops.

Instead: answer, then add a detail or ask a question back.

• “Yes, I came by train. I live in Bolton, and it’s only a ten-minute walk from the station.”
• “Yes, thanks. Have you worked here long?”

Now the other person has something to respond to, maybe “Oh, you live in Bolton? I used to work there.” It might not happen every time, but you’ve created a chance for a real conversation.

The hidden question: Do you want this job, or just any job?

Even if you’re applying for lots of jobs, you want each interviewer to feel you want their job. Before the interview, look at the company’s website and values, recent blog posts and LinkedIn posts.

Instead: use your research in two places.

• In the small talk: “I saw on LinkedIn that you’ve opened a new facility in Liverpool. How’s that going?”
• In your answers: “I noticed one of your values is continuous improvement. That’s important to me too. For example…” Then give evidence.

Remember, an interview is a two-way conversation. They’re checking whether you fit the team, and you’re checking whether this is a company where you really want to work.

The hidden question: Are you being genuine?

Preparation is essential, but memorised answers cause three problems:

• If you forget one word, you can lose everything. It’s hard to recover, and it’s obvious you’ve learned a script.
• The question may be different from the one you prepared. You might prepare for “Tell me about yourself”, but hear “Could you walk me through your CV?” or “Can you talk me through your relevant experience?” Each needs a slightly different answer.
• Memorised answers sound flat. Your voice becomes monotone (one level, with no variation), and your personality disappears.

Instead: prepare key points and a few starter phrases, then practise talking around them in different ways.

• “I’m a mechanical engineer with eight years’ experience.”
• “The most relevant part of my experience is…”

One more tip: when you talk about your experience, remember how you felt. Were you excited? Proud? That feeling comes through in your voice, and it’s far more powerful than saying “I’m really passionate about engineering.” It’s not only what you say; it’s how you say it.

The hidden question: Can you communicate clearly under pressure?

If you don’t fully understand a question, don’t guess and give one of your prepared answers. UK interviewers are often too polite to interrupt, so you could speak for a minute answering the wrong question. They will notice.

Asking for clarification isn’t a weakness. It shows that accuracy matters to you, and it’s professional.

Instead, try:

• “Sorry, could you repeat that?”
• “Could you rephrase that?”
• “Just to check, do you mean…?” Then repeat the question in your own words.

Of course, if you do this for every question, it won’t look professional. Practise your listening skills and research typical interview questions, so very little surprises you.

The hidden question: Can you actually do it?

This matters most in competency-based questions, such as “Tell me about a time when you showed your organisational skills.”

It’s easy to make a claim like “I’m very organised. I always plan everything.” Or a general statement: “When I worked at Company X, I organised all the projects.” That names a company, but not a specific time, so anyone could say it. In the UK, you need evidence to support your claim.

Instead: give one specific example. “When I worked at Company X, I managed the installation of a new product line.” Then explain:

1. the situation
2. what you did
3. the result

This is based on the STAR method (Situation, Task, Action, Result). I’ll cover it in more detail in another video.

Also, say “I”, not “we”. Yes, you work in a team, but the interviewer wants to know your role in the project.

The hidden question: Is this person willing to learn and adapt to our company?

Saying you have every skill might sound impressive, but we all have areas to improve. UK companies want people who are adaptable and always learning.

Instead, show this in two ways:

1. Reflect at the end of your examples. After describing something you achieved, add what you learned or what you would do differently next time.

2. Give a real answer to the “weaknesses” question. It’s tempting to say a positive “dressed up” as a negative, like “I’m a perfectionist” or “I work too hard.” Interviewers have heard these answers many, many times.

Choose a real weakness that isn’t a core skill for this job. Then, and this is the key, explain how you’re improving it. For example:

“I sometimes give too much technical detail when I’m working with non-technical colleagues. So I’m working on summarising my main points before meetings and highlighting what they really need to know.”

This is honest, it doesn’t affect your ability to do the job, and it shows you’re willing to learn.

The hidden question: Are you really interested in us?

At the end, the interviewer will almost certainly ask, “Do you have any questions for us?” Saying “No, I think you’ve covered everything” is OK, but it can sound like you’re not very interested.

Instead: prepare two or three questions about the business and the role.

• “Who would I be working with day to day?”
• “What are the biggest challenges the team is facing right now?”
• “I saw you’ve opened a new facility. Would this role involve working there?”

That last one shows you’ve done your research, too. Avoid focusing on pay or holidays at this stage. Use this time to find out more about the actual work.

To sum up, UK interviewers have already checked your skills on your CV. They already think you could be a good fit. In the interview, they want to know how you communicate, how you connect with people, and whether you’ll fit into the team.

None of this is about analysing your English. You don’t need perfect English to do well in an interview. You need a communication strategy, and that is something you can learn.

Keep these seven mistakes, and the hidden questions behind them, in mind when you practise for your next interview.
