Language skills on your CV: how a second language boosts your career

If English is your first language, it's tempting to think language skills don't matter much for your career. After all, English is the default in so many workplaces. But that's exactly why a second language stands out: fewer native English speakers have one. This guide looks at how language skills on your CV can change your opportunities, how to describe your level honestly, and how to handle the moment someone switches to Spanish in the interview.

Why does a second language matter for your career?

A language on your CV says more than "I can speak Spanish". It tells an employer several things at once:

• You can communicate with more people: customers, suppliers, colleagues in other offices.
• You've stuck with something hard. Reaching a useful level takes months or years of consistent effort.
• You're comfortable with other cultures, which matters in international teams.
• You're curious and adaptable, qualities employers often mention but can rarely test.

It's rarely the single thing that gets you a job. But it can be what makes your application memorable, or what qualifies you for a role that involves a particular market.

Which jobs value languages most?

Languages are useful in almost any field, but they can make a real difference in:

• Customer-facing roles: sales, support, hospitality, tourism.
• International business: export, procurement, logistics, partnerships.
• Healthcare, education and public services, especially in communities where Spanish is widely spoken, as it is in many parts of the US.
• Marketing and content, where understanding a local audience goes beyond translation.
• Tech and remote-first companies with teams across Europe and Latin America.

Spanish is a particularly practical choice for English speakers. It's spoken across Spain and most of Latin America, and it's widely used in the United States.

How to put language skills on your CV

Vague labels like "conversational", "good" or "fluent" mean different things to different people. The clearest way is to use the CEFR (Common European Framework of Reference), the A1 to C2 scale developed by the Council of Europe. It's widely recognised in Europe and increasingly understood elsewhere. If you're not sure what each level means, our guide to the CEFR language levels explains them simply.

A few tips:

• Give the level, then a short proof. For example: Spanish: B1 (CEFR). Handle routine customer emails and calls.
• Mention certificates if you have them, such as the DELE or SIELE for Spanish, with the year.
• Be honest. If you write B2, expect the interviewer to test it. Overstating your level is the quickest way to lose credibility.
• Don't hide a lower level. An A2 can still be worth listing, especially if you're actively improving: Spanish: A2, currently studying towards B1.
• Put it where it's relevant. If the job involves Spanish-speaking clients, mention the language in your summary, not just at the bottom.

What level do employers expect?

As a general guide, B1 is often seen as the point where you can start using a language at work for routine tasks, and B2 is a common requirement for roles where you'll work in the language every day. Our article on what B1 Spanish means describes that level in detail. But requirements vary enormously, so read the job description carefully.

What if the interview switches to Spanish?

If you list a language, be ready to use it. Some interviewers will switch for a few minutes to check. Prepare for that:

• Practise a short introduction: who you are, what you do, why you want the role. Me llamo Sarah, trabajo en marketing desde hace cinco años y me interesa este puesto porque...
• Prepare to talk about your experience in the past tense. En mi último trabajo, gestioné un equipo de cuatro personas.
• Have a few phrases to buy time or ask for clarification: ¿Puede repetir la pregunta, por favor?, Déjeme pensar un momento.
• Don't panic about mistakes. Interviewers are usually checking whether you can communicate, not whether every ending is perfect.

Decide in advance whether to use tú or usted. In many Spanish workplaces tú is normal, but in an interview, especially in Latin America, starting with usted and following the interviewer's lead is a safe choice.

Languages and remote work

Remote work has made it more common to work with people in other countries without moving. A second language can help you:

• Join international teams and communicate better in informal chats, not just formal meetings.
• Work with clients in a new market from home.
• Build closer relationships with colleagues whose English is good but not their most comfortable language.
• Keep options open if you ever want to relocate.

Even if meetings are in English, being able to switch to Spanish for small talk or a quick message can build trust.

How to build work-ready Spanish

• Learn the language of your field: the twenty or thirty words you'd use every day.
• Practise emails and calls, the most common workplace tasks.
• Keep a steady routine. Short daily practice is easier to fit around a job than long weekly sessions.
• Get real practice: a colleague, a language exchange, a weekly call.

Parlumi's courses go from A1 to C2 and use the CEFR levels, so it's easy to know what to write on your CV as you progress. However you learn, the most valuable thing you can say about your languages isn't the label. It's what you can actually do with them.
