Hiring a translator, interpreter, editor, or localization specialist can make or break your project. Pick the right person, and your launch goes off without a hitch. Pick the wrong one, and you’re looking at costly delays, awkward mistranslations, and a lot of unnecessary stress.

But if you don’t speak the language yourself, how do you actually know who’s good?

Here is a practical, no-nonsense guide to evaluating candidates so you can kick off your next project with total confidence.

1. Dig deeper

Being bilingual is just the baseline —it doesn’t automatically make someone a great professional. When you’re looking at a resume, a ProZ profile or a website, keep an eye out for these five things:

• Real industry expertise: Language skills are great, but niche knowledge is what makes all the difference. A legal contract needs a legal brain; a medical device manual needs a healthcare expert; marketing copy needs a creative writer who gets local culture. Look for someone who already speaks your industry’s slang: read through their resume or their About section to evaluate if they are the right fit for your project.
• The right kind of experience: Don’t just look at the number of years they’ve been working. Pay attention to what they’ve been doing. Someone who has spent five years translating the exact type of software you’re building is going to be a much better fit than a generalist with twenty years of mixed experience. When looking at a ProZ profile, you may want to pay attention to the Specializations section and their Project history to assess their expertise.
• Portfolios & samples: Check out their past work, websites, or case studies to get a quick sense of their writing style and attention to detail. On ProZ profiles, this is listed under Work samples.
• Client feedback: Read reviews and testimonials, and look for patterns rather than a single glowing or grumpy comment. Are people constantly praising their communication? Do they consistently hit deadlines? That’s what you want.
• Industry love: Are they involved in professional associations or continuing education? Pros who care about their craft stay active in their community. On ProZ, you can find courses and events attended under Certifications, and, under Activity, see if they contribute with translation help, glossary entries and forum discussions to get a sense of them as a peer.

2. Look beyond the price tag

It’s incredibly tempting to just pick the lowest bid, but in the language world, you usually get what you pay for. When you’re looking over quotes, compare them side-by-side on these fronts:

• What’s actually included? One quote might look cheaper because it’s just for the raw translation. A slightly higher quote might include a second editor, a proofreader, formatting, and quality checks. Make sure you’re comparing apples to apples.
• The timeline: Is the deadline realistic? If a timeline seems suspiciously fast, they might be cutting corners. A true pro will give you an honest estimate of how long quality work takes.
• The fine print: Is the price based on your final, clean files, or a rough draft? Is it an editable format? Clarifying these assumptions early keeps everyone happy and prevents surprise invoices later.

3. Ask the right questions

Before you sign any contract, have a quick chat and throw these questions their way. Their answers will tell you everything you need to know:

• “Have you tackled a project like this before?” (Again, specific experience wins.)
• “How do you handle industry terminology?” (Look for mentions of glossaries, style guides, or specialized software that keeps branding consistent.)
• “Who is actually doing the work?” (If you’re hiring an agency or a team, you’ll want to know if it’s one dedicated person or a revolving door of freelancers.)
• “What’s your QA process?” (Good pros always have a system for catching mistakes before they hit your inbox.)
• “How should we handle questions?” (The best projects are collaborative. You want someone who isn’t afraid to raise their hand and ask for clarification if something in your text is ambiguous.)

4. Over-communicate your expectations

Most project disasters don’t happen because the linguist is bad —they happen because of poor communication. Before anyone starts typing, make sure you are both 100% aligned on:

• Who the audience is (and the tone they prefer).
• Where the content will live (a website, a legal court, a print brochure?).
• Formatting and deadline milestones.

Pro-tip: If you have a style guide, a list of preferred brand terms, or even past translations you actually liked, hand them over! It gives your hire a massive head start.

5. Don’t skip the security talk

If you’re handing over sensitive company data, financial info, or unreleased product details, don’t leave security to chance. Ask them upfront:

• Are they willing to sign an NDA?
• How do they securely share and store files?
• What is their data retention policy?

A real professional won’t blink at these questions; they’ll already have secure processes in place.

6. Trust the “vibe check”

The most qualified person on paper isn’t always the best person for the job. Pay attention to how they treat you during the hiring process:

• Are they responsive, or do they take three days to reply to an email?
• Do they seem genuinely interested in helping you reach your goals?
• Are they asking you smart questions about the project?

How someone communicates before you hire them is a preview of how they’ll communicate during the project.

The bottom line

Finding the right language professional takes a little upfront effort, but it pays off massively in the long run. By looking past the price tag, asking the right questions, and setting crystal-clear expectations, you’ll find a partner who doesn’t just translate words —but actually helps your project succeed.

Prefer to skip the vetting process altogether?

Let’s be honest: finding the right language pro takes time. Between digging through profiles, comparing quotes, checking references, and managing different people for different languages, it can quickly turn into a full-time job —especially if you’re balancing a massive, fast-moving, multilingual project.
