Choose on evidence of skill in your own meeting's field, not on a résumé or a price: a client can check five things directly, starting with whether someone other than the interpreter has scored them on a test in that field.

Summary: A résumé and a price do not show whether an interpreter will hold up in your meeting. This guide sets out five criteria a client can check directly, without being an interpreter, so you choose on evidence of skill rather than self-reported experience.
Why the usual inputs fall short
Most interpreter choices rest on two pieces of information: a résumé and a price.
The résumé is experience the interpreter reports about themselves. The price is how the interpreter, or the agency, positions them in the market. Both come from the supplier side. The client has no independent way to check either.
That is where things go wrong. An interpreter with a long career can still mistranslate one line of dosage instructions at a medical conference. A member of an international association can still compress a single modal verb in an M&A negotiation and change what the other side thinks was promised. Self-reported experience is the weakest verification tool at exactly the moment the stakes are highest.
This guide offers a different approach: five criteria the client can check directly. I am Paul Dahoon Kim. I have worked as a Korean-English interpreter across around 100 engagements and now run MetaPret, an interpreter matching platform. These five criteria come from looking back at the engagements where accuracy broke down, not from a marketing brief.
Criterion 1: Domain skill that someone else has tested
This is the most important criterion, so it comes first.
What to look for: whether the interpreter has performed a real interpretation task in your engagement's field and been scored on it by someone other than themselves.
What not to rely on: self-reported counts such as "five M&A engagements," or the fields an interpreter says they are good at.
Why it comes first: interpreting skill is domain-specific. An interpreter who is strong in M&A negotiation can be weak at a medical conference. One who is strong on IR calls can struggle on a factory floor. General Korean-English ability fits on one line of a certificate, and that line says almost nothing about the field of your meeting.
How to check it:
a) A domain test before the booking. Ask whether the interpreter has taken an interpretation test in your field, scored by a third party, and whether you can see the result. (This is the problem MetaPret's per-engagement test is built to solve.)
b) References from senior interpreters in the same field. The interpreting community is small and reputations travel accurately within a domain.
c) Field-specific work samples. Where they exist: recordings from comparable engagements, client references from the same field.
"Five engagements" that the interpreter reports is not verification. A score that someone else assigned is.
Criterion 2: The right mode for the format
Interpreters are human. Few are equally strong in every mode: escort, consecutive, simultaneous, and whispered.
What to look for: the mode your meeting actually needs, and tested skill in that mode.
Why it matters:
An interpreter who is strong in consecutive works with different cognitive processing from what a simultaneous booth demands. Listening, memory buffering, and compression are separate skill sets. "I can do both" often falls apart on the day.
An interpreter who is strong in escort work can sound too light in a formal negotiation. The warm register that works on a site visit reads as a lack of weight across the negotiating table.
How to check it:
a) Ask what share of the interpreter's recent work was in the mode you need. Someone whose work is mostly escort interpreting is not the default choice for a simultaneous conference booth.
b) Check that the quote reflects the mode. A quote for simultaneous work at an escort-interpreting rate is a signal worth asking about.
c) If you use a platform, check whether it matches by mode or routes every request from one undifferentiated pool. A single pool averages these differences away.
Criterion 3: City and regional context
This criterion breaks most often when an interpreter from one market takes a job in another.
What to look for: whether the interpreter knows the business culture of the city where the meeting happens.
Examples:
- A Tokyo-based interpreter on an Osaka job may not follow Kansai dialect.
- A Seoul-based interpreter in Busan may be less at home with the regional dialect and local business culture.
- An English interpreter used to Southeast Asian business may miss the pace of a meeting with a US East Coast team.
- A Korean interpreter fluent with native English speakers can stumble on the pronunciation and grammar patterns of a Japanese speaker using English as a second language.
Why it matters: interpretation is not word conversion. It moves meaning from one cultural context to another. When the regional context is off, the words can be right and the meaning still wrong.
How to check it:
a) Whether the interpreter has lived in the city or worked there regularly.
b) A short conversation about your industry in that city. After ten minutes, can they talk naturally about the local business nuances?
c) If you use a platform, ask how it sources for the city of the meeting, rather than routing from one global list.
Criterion 4: What the interpreter asks for before the meeting
This criterion shows professional habits more honestly than any other.
What to look for: what material the interpreter requests before accepting or preparing.
Good signs:
- Asks for the agenda, slides, and participant list
- Asks for a glossary, or offers to build one with you
- Asks for notes from earlier meetings, if any
- Requests a short call to understand what you want out of the meeting
Warning signs:
- "An interpreter works on the spot. I don't need materials."
- Negotiates the rate but shows no interest in the content
- Plans to arrive 30 minutes before and walk in without materials
Why it matters: a large part of interpreting accuracy is decided before the interpreter reaches the room. An interpreter who has read the material, settled the terminology, and learned who the participants are will be more accurate on the day than the same person walking in cold.
An interpreter who never asks for material is relying on raw skill alone. Over many engagements, a solid interpreter who prepares every time tends to deliver more reliable outcomes than a brilliant one who skips the homework.
Criterion 5: What happens when a match falls short
This criterion tests the channel you book through, more than the interpreter.
What to look for: a stated policy for what happens if the interpreter does not meet expectations.
Good signs:
- How problems are handled is written down before you book
- Responsibility terms are agreed in advance
- Complaints get a response within a stated window, such as seven days
Warning signs:
- "The job is done, so no refund."
- "We'll give you a discount next time," which moves responsibility for this engagement to a future one
- No stated policy at all
- Client complaints never reach the interpreter
Why it matters: in a market without accountability, a poor match costs the client and the interpreter moves on to the next job. Nobody learns. A channel with a stated policy catches poor matches inside the system, so the interpreter and the channel both improve.
At MetaPret, if a match falls short of expectations, contact cs@metapret.net within seven days of the engagement and we will work with you to resolve it.
Checklist: five questions to ask before you book
Ask these of the interpreter, or of the channel matching you:
- Tested domain skill: "Has this interpreter taken a scored interpretation test in this field, and can I see the result?"
- Mode fit: "How much of this interpreter's recent work was in this mode (escort, consecutive, simultaneous, whispered)?"
- City context: "Has this interpreter lived or worked in this city?"
- Preparation: "What material will you need from us, and how many days before the meeting?"
- Accountability: "What happens if the match does not meet expectations?"
An interpreter or channel that cannot answer these clearly is worth avoiding for a high-stakes meeting, even at a lower price.
How MetaPret handles the five criteria
- Tested domain skill: every interpreter goes through a profile review by the MetaPret team at registration. For each request, candidates then take a test written in that request's field, in both directions of the language pair. MetaPret selects from the candidates whose test was confirmed, and the client receives the confirmed interpreter's profile and why their experience fits the request. Individual scores are not shared.
- Mode fit: test passages are built from the interpretation mode and meeting format on the request.
- City context: candidates are sourced and tested for the city and dates of each request. Verified supply is deepest in Seoul today, and verification travels to wherever your meeting is.
- Preparation: after the match, the interpreter and the client go through a preparation step to exchange the agenda, slides, and participant list.
- Accountability: if a match falls short, contact cs@metapret.net within seven days and we will work it out with you.

FAQ (FAQPage schema)
Q: Is an interpreter's résumé useless?
A: No. It is a starting point, not the finish line. Use the résumé to narrow the list, then check candidates against the five criteria above.
Q: Is a member of an international interpreters' association always a good choice?
A: Association membership is a credible signal for general conference interpreting. It does not test skill in a specific field such as medicine, law, or M&A. Domain-specific verification is still needed.
Q: Is a Senior interpreter always the better choice?
A: Match the interpreter to the weight of the meeting. A routine business meeting does not need the most senior interpreter available. An M&A negotiation or a medical conference should not go to someone at entry level. Matching the engagement's stakes to the interpreter's level matters most.
Q: Does booking the same interpreter regularly lower the price?
A: Some interpreters offer a discount for recurring work. The larger benefit is that the interpreter builds up context on your business, so accuracy rises from one meeting to the next.
Q: What is the most common mistake when choosing an interpreter?
A: Making price the first criterion. Interpreter cost is a small share of what the meeting puts at stake: the event budget, the attendees' time, and the value of the decision being made in the room. Saving on that small share while putting the meeting's accuracy at risk is, in hindsight, the most expensive choice.
