How to prep a candidate with English as a second language

Preparing a candidate with English as a second language (ESL) requires prioritising clarity over speed and focusing on their core competencies rather than their linguistic polish.

By providing interview questions in advance, using written prompts, and allowing extra time for processing, you create an environment where their actual skills – not just their fluency – can shine through. At Compono, we have spent years researching how to look past the surface of a CV to find the real person underneath, ensuring that language barriers do not become barriers to diversity.

Key takeaways

• Send interview questions or themes 24–48 hours in advance to allow for vocabulary preparation and mental processing.
• Utilise visual or written aids during the interview to reduce the cognitive load of purely auditory processing.
• Focus on 'work personality' and technical skills rather than accent or grammatical perfection to avoid unconscious bias.
• Provide a clear agenda and explain the interview format early to reduce anxiety and build candidate confidence.
• Allow for longer pauses and silence, giving the candidate space to translate their thoughts into English without feeling rushed.

The hidden cost of the fluency trap

You have likely been there before. You are sitting across from a candidate who has an incredible track record, but the conversation feels clunky. There are long pauses, some unusual word choices, or an accent that requires a bit more focus to understand. It is easy to walk away from that meeting thinking they 'just aren't a culture fit' or that 'communication might be an issue'.

But more often than not, what you are actually experiencing is the 'fluency trap'. This is the mistaken belief that someone’s ability to speak English quickly is a direct reflection of their intelligence or their ability to do the job. When we fall into this trap, we miss out on brilliant engineers, strategic thinkers, and creative problem solvers just because they didn't have the right idioms at their fingertips.

The reality is that interviewing is stressful for everyone, but for someone navigating their second or third language, that stress is doubled. They are performing a high-stakes mental marathon – translating your questions, formulating an answer, and then translating that answer back into English – all in real time. If you don't prep them properly, you aren't testing their skills; you are just testing how well they handle a linguistic ambush.

Level the playing field before the interview starts

Preparation starts long before you jump on a Zoom call or meet in a boardroom. The most effective way to prep a candidate with English as a second language is to remove the element of surprise. In a typical interview, we value 'thinking on your feet', but for an ESL candidate, this often just rewards those with the fastest translation speed, not the best ideas.

Try sending the core interview questions or at least the key themes 24–48 hours before the meeting. Some managers worry this 'gives away the answers', but if the role isn't about live debate or high-pressure verbal sparring, why does it matter? You want to see their best work, not their ability to guess what you are going to ask. Giving them time to look up specific industry terms ensures they can speak about their experience with precision.

You should also provide a clear breakdown of who will be in the room and what the format looks like. Knowing that the first fifteen minutes will be a technical deep dive and the last ten will be for their questions allows them to mentally categorise the vocabulary they will need. It reduces the cognitive load, letting them focus on the 'what' of their experience rather than the 'how' of their English.

Reframing communication as a two-way street

We often treat communication as a one-sided responsibility – the candidate has to make themselves understood. But as an interviewer, you have a massive role to play in how well that candidate performs. If you speak quickly, use heavy slang, or ask 'double-barrelled' questions (two questions wrapped in one), you are making the hurdle higher than it needs to be.

When you are in the room, keep your language simple and direct. This doesn't mean talking down to the candidate; it means being an effective communicator. Avoid metaphors like 'ballpark figure' or 'touching base' which can be confusing if English isn't your first language. Instead, ask for 'estimates' or 'following up'. These small shifts in your behaviour make it significantly easier for the candidate to follow the thread of the conversation.

If you're curious about how your own natural style might be landing with others, Hey Compono can show you your work personality in about 10 minutes. Understanding if you’re a 'Campaigner' who talks in big-picture metaphors or a 'Coordinator' who values rigid structure can help you adjust your approach to be more inclusive for every candidate you meet.

Using visual aids to bridge the gap

Auditory processing – the act of hearing, decoding, and understanding speech – is often the first thing to fatigue during a long interview. By the forty-minute mark, an ESL candidate might be struggling to keep up with complex verbal instructions. This is where visual and written aids become your best friend.

If you are setting a task or a hypothetical scenario, provide it in writing. Having the text in front of them allows the candidate to refer back to the details without having to ask you to repeat yourself, which many candidates are too polite or nervous to do. It grounds the conversation in facts rather than fleeting sounds.

Digital tools can also help. If you are interviewing remotely, encourage the use of the chat function for complex numbers, names, or technical terms. This ensures that no information is lost in translation. It’s about creating a 'multi-modal' experience where the candidate has more than one way to succeed. When we focus on these practical supports, we move away from judging a person's accent and start judging their actual output.

The power of the pause

In Australian work culture, we tend to be uncomfortable with silence. We jump in to fill gaps in conversation, often finishing people's sentences for them to be 'helpful'. When prepping and interviewing an ESL candidate, you must resist this urge. Silence is not a sign of a lack of knowledge; it is the sound of a brain working hard to find the right words.

Give the candidate an extra five to ten seconds after you ask a question. Let them sit with it. If they look like they are struggling, don't rephrase the question immediately – that just gives them a second set of words to translate. Instead, wait. If you do need to clarify, use different words entirely rather than just repeating the same sentence louder or slower.

There is actually a way to figure out which of these patterns fits you – take a quick personality read and see what comes up. Some people are naturally more patient, while others are 'Doers' who want to get to the point quickly. Recognising your own 'Work Personality' helps you realise when your desire for speed might be accidentally shutting down a brilliant candidate who just needs a moment to find their voice.

Focusing on work personality over linguistic polish

At the end of the day, you aren't hiring a dictionary. You are hiring a person who can solve problems, work with a team, and contribute to your culture. This is why we advocate for looking at the 'Work Personality' – the underlying traits and motivations that drive how a person actually performs on the job.

A candidate might struggle with the past tense in an interview, but their assessment might show they are a high-performing 'Auditor' with an incredible eye for detail, or a 'Helper' who will go above and beyond for their teammates. These traits are universal and exist independently of what language someone speaks. When you prioritise these objective insights, you make better hiring decisions that aren't skewed by unconscious bias against accents or dialects.

By the time the interview ends, your goal should be to have a clear picture of the candidate’s capabilities. If you’ve prepped them well – by giving them questions early, using written prompts, and allowing for silence – you can be confident that the 'data' you’ve gathered is accurate. You’ve seen the person, not just their English level.

Key insights

• Preparation for ESL candidates should focus on reducing cognitive load through early disclosure of questions and themes.
• Effective interviewing requires the recruiter to adapt their communication style, avoiding idioms and complex sentence structures.
• Visual and written prompts are essential tools to ensure technical details are understood correctly by both parties.
• Silence is a functional part of the ESL interview process and should be respected rather than interrupted.
• Objective assessments of work personality provide a fairer metric for success than verbal fluency alone.

Frequently asked questions

Is it fair to give one candidate the questions early but not others?

Fairness doesn't always mean treating everyone exactly the same; it means giving everyone an equal opportunity to succeed. If a candidate is navigating a language barrier, giving them questions early removes a disadvantage, bringing them up to the same starting line as a native speaker.

How do I know if their English is 'good enough' for the role?

Focus on the specific requirements of the job. Does the role require writing complex legal briefs, or is it about technical execution within a team? If they can communicate the necessary information – even with an accent or minor errors – they can likely do the job effectively.

What if the candidate seems very nervous because of their English?

Acknowledge it early. A simple 'I know interviewing in a second language is a huge task, so please take your time' can lower their cortisol levels instantly. When a candidate feels seen and supported, their performance improves significantly.

Should I use a translator for the interview?

Generally, it is better to use written aids and simplified speech first. A translator can sometimes add a layer of separation that makes it harder to build a personal connection. However, for highly technical roles where precision is life-or-death, a translator might be appropriate.

How can I avoid bias when listening to an accent?

Be aware of 'accent prestige' – the tendency to favour certain accents over others. Focus on the content of the answer. Taking notes based on the 'Work Personality' traits they demonstrate (like 'The Doer' or 'The Advisor') helps keep your evaluation objective and grounded in facts.
