What should a busy buyer put in the scorecard?
Start with the work the hire must complete. Write down who will use it, what a successful release looks like, and who will review it. Then turn those outcomes into interview criteria.
For this role, make the boundary between voice work and web work explicit. If the developer will also own a React dashboard, name that responsibility. If another engineer owns the dashboard, leave React out of the required skills.
A broad job title leaves too much room for interpretation. One interviewer may look for a front-end specialist while another expects someone who can own the whole voice experience. Resolve that difference before candidates spend time interviewing.
Copy this role definition
Fill in these fields with the engineering manager and the person who will approve the hire.
| Field | What to enter |
|---|---|
| Role purpose | The user problem this developer will help solve |
| First release | The specific experience or change they will deliver |
| Voice ownership | The conversation flows and failure paths they will own |
| Web ownership | Any React interface included in the role |
| Existing system | The code, services, and access the hire will inherit |
| Required experience | Skills needed to complete the first assigned work |
| Teachable skills | Skills your team has time and staff to teach |
| Work schedule | Required shared hours, named time zone, and support duties |
| Manager | The person who sets priorities and reviews delivery |
| Budget | Approved cost range and what it must include |
| Decision owner | The person who makes the final hiring call |
Keep the first release narrow enough to assess. "Own our voice strategy" gives an interviewer little to test. "Deliver the agreed account-status flow and document its failure paths" gives the panel something concrete.
Do the same for seniority. If you need independent ownership, say which decisions the developer must make without waiting for a lead. If a senior engineer will review every design, describe that support.
Set early outcomes before selecting interview questions
Use the following as a planning template. These are suggested checkpoints, not promises about how quickly a new hire will deliver.
| Checkpoint | Example outcome | Evidence to review |
|---|---|---|
| First month | Understand the existing flow and complete a bounded change | Reviewed change, test results, and a short system walkthrough |
| Second month | Own an agreed feature through review | Accepted work, documented failure handling, and release notes |
| Third month | Maintain the feature and propose a justified improvement | Issue history, a handoff document, and a scoped proposal |
Adjust these checkpoints for access delays and the state of your code. A developer cannot release work while waiting for credentials or a product decision.
For each outcome, name the person who accepts it. A product lead might approve the user flow while an engineering lead approves the change. Write down what happens if their requirements conflict.
If your actual need is to hire a React JS developer for an internal console, write the role around that console. Keep voice experience as a separate requirement only when the person will perform that work.
Separate requirements from preferences
Before the search starts, challenge every must-have. Ask which first-release task would fail without that skill and whether someone on your team could teach it.
Keep direct experience mandatory when the hire must make those decisions alone from the start. Put a tool in the preferred column when the team can support a capable developer learning it.
Record exclusions too. If mobile delivery, visual design, or overnight support belongs to another team, say so. This gives candidates a clear view of the job and keeps interviewers from adding requirements during the final discussion.
What does the data say about budget and evidence?
The US median annual wage for software developers was $135,980 in May 2025, according to the BLS Occupational Outlook Handbook.
Use that figure as a broad US wage benchmark. It is not a quote for this role, a seniority-specific rate, or a total employment budget. It also does not establish what a particular candidate should earn.
Before comparing hiring options, put each quote on the same basis. Ask whether it includes payroll costs, benefits, equipment, and placement fees. Record the billing currency and any terms that can change the price.
Keep compensation separate from the technical score. Otherwise, a lower quote can quietly become evidence of ability during the final discussion.
Build the budget around your actual responsibilities. If your team must provide close technical review, reserve that manager's time before approving the hire. Do not assume a lower hiring cost also means less work for your existing engineers.
Use a rating scale with observable anchors
The following scale is a proposed hiring tool, not a market statistic. Agree on it before interviews begin.
| Rating | Meaning | Evidence needed |
|---|---|---|
| 1 | Does not meet the requirement | Cannot complete or explain the task despite reasonable clarification |
| 2 | Can contribute with close support | Completes part of the task but needs repeated guidance |
| 3 | Meets the role requirement | Completes the task and explains decisions with the expected level of support |
| 4 | Exceeds the role requirement | Handles relevant edge cases and explains tradeoffs beyond the basic task |
| Not assessed | No usable evidence yet | Requires a focused follow-up before a decision |
Do not turn "Not assessed" into a low score. A panel that forgot to ask about a requirement has an interview gap to close.
For each rating, save a short evidence note. "Strong communicator" is hard to compare. "Explained the failed request, named its user impact, and proposed a next step" is useful at the decision meeting.
Copy this candidate scorecard
Mark each row as required, preferred, or outside the role. Add the interviewer responsible for gathering the evidence.
| Criterion | Suggested assessment | Evidence to record |
|---|---|---|
| Voice flow judgment | Walk through a user request and an unclear response | How the candidate clarifies intent and helps the user recover |
| Service integration | Review a small task involving an external response | Handling of failed requests and unexpected data |
| Code quality | Discuss a bounded change | Whether the candidate can explain and revise their code |
| Testing | Ask for checks around the proposed change | Which failures the checks would catch |
| Release ownership | Discuss a past release or a sample release plan | Review steps, rollback thinking, and handoff details |
| React delivery, if required | Review a small interface change | State handling, error feedback, and accessible interaction |
| Team communication | Request a short written handoff | Whether another engineer can act on it |
| Schedule fit | Confirm actual working hours | The agreed overlap and any support limits |
Require a passing assessment for every must-have row. A high overall average should not erase a failure on a requirement the role cannot do without.
Calibrate the panel with a sample answer
Before interviewing, have reviewers score the same fictional response. Compare what each person counted as acceptable work and what support they assumed the developer would receive.
For example, a candidate may describe the normal account-status flow but omit what happens when the service returns an error. Record that omission against the relevant criterion. Avoid turning it into a broad claim that the candidate lacks judgment.
If reviewers disagree, revise the scoring anchor before using it on applicants. Keep the standard fixed once interviews start. When a genuine scope change requires new criteria, reassess earlier candidates against the revised requirements.
How do hiring models differ for nearshore and Latin American roles?
Choose the model based on who will find the person, handle the employment arrangement, and manage delivery. Keep the candidate scorecard consistent across those options.
Use this table to structure the conversation. Confirm the actual division of work in the contract.
| Model | What to clarify | What your scorecard still needs |
|---|---|---|
| Direct hire | Who runs the search and handles employment administration | Full evidence of role fit and manager capacity |
| Recruiting agency | Where recruiting support ends and your responsibilities begin | Your own final assessment of the candidate |
| Employer of record | Who finds and assesses the person, and what employment services are included | Technical evidence and a named day-to-day manager |
| Managed recruiting and placement partner | Which search, assessment, and ongoing services are included | A candidate decision tied to your delivery goals |
| Project outsourcing | Who owns staffing, delivery decisions, and acceptance | Project acceptance criteria and ownership boundaries |
If you want an individual to join your team, assess their ability to work within your review process. If you want a finished project, define the deliverable and its acceptance checks before comparing proposals.
A project contract also needs a handoff plan. Name the repositories, access rights, and operating notes your team should receive. Ask who will fix defects after acceptance and how changes to scope are priced.
For an individual hire, identify who handles problems after joining. Separate feedback about the developer's work from payroll questions and contract changes. Put a named contact against each responsibility so the new hire knows where to go.
Define overlap as a schedule
"US hours" leaves several questions open. Put the required meeting window in the scorecard, with a named time zone. Separate ordinary collaboration from on-call duties.
Bogotá is UTC-5 without daylight saving time. Buenos Aires is UTC-3 without daylight saving time. See the IANA South America time zone data.
Mexico City is UTC-6 without daylight saving time, while Tijuana follows US daylight saving changes. See the IANA North America time zone data.
Confirm the schedule for both parts of the US clock-change cycle. Ask the candidate to state the resulting local hours and whether they can sustain them.
Write down which meetings require live attendance and which updates can be written. Include how the team handles planned leave and urgent issues outside shared hours. A candidate should be able to accept the actual schedule before accepting the role.
Assess communication through actual work. A short design discussion and a written handoff give the panel something to review. Avoid using a country or city as a substitute for an individual assessment.
What should you ask a provider before accepting a shortlist?
Ask for evidence against the scorecard with each candidate submission. A resume and a general assurance that someone passed screening leave your panel to repeat the assessment.
Request the candidate's contribution to a relevant project, the tasks used during screening, and the areas your interview still needs to cover. Keep those requests consistent across providers.
Ask how the screening maps to your work
Useful questions include:
- Which scorecard requirements did you assess directly?
- What did the candidate complete without help?
- Which parts of the role require further assessment?
- Who reviewed the technical work?
- Can our interviewer discuss the work with the candidate?
- How do you handle confidential work samples and candidate consent?
Ask for the distinction between voice experience and React experience in writing. A candidate may have good evidence for one part of the role and need further assessment for the other.
For a portfolio review, choose one relevant project and stay with it. Ask what the candidate personally changed, what went wrong, and how they checked the result. Give them room to explain constraints without sharing a former employer's private code.
Use one bounded work sample
Write a fictional task that resembles the role. For example, ask the candidate to outline an account-status interaction, handle an unclear request, and explain what happens when a service fails.
Give candidates a small set of sample responses and a clear description of the user. Ask what they would confirm before showing or speaking account details. Use fictional records and keep production credentials out of the exercise.
If React work is required, add a small interface task that reflects the actual job. Keep it separate enough that interviewers can score each skill.
State the expected time, allowed tools, and review criteria in advance. Pay for substantial take-home work, and avoid assigning useful production work as an unpaid hiring exercise.
If AI tools are allowed, ask candidates to explain the result and make a change during the review. Score their understanding and judgment under the policy you set.
Give candidates the same instructions. Offer reasonable accommodations and assess the skill the job needs, rather than speed on an unrelated puzzle.
Test how the candidate changes an answer
During the review, introduce a small change to the fictional task. The user might cancel midway through the flow, or the service might return an incomplete result.
Ask the candidate to explain which parts of their approach change. Let them revise their answer and record whether they can explain the effect on the user.
This follow-up should stay within the original task. Avoid adding an unrelated architecture problem after a candidate has prepared for a small code review. Tell reviewers which criterion the change tests and what a passing answer should demonstrate.
Ask what the commercial terms mean for this role
Request a written quote with the included services and any extra charges. Ask what triggers a price change and how notice, replacement, or cancellation works.
For timing claims, ask when the clock starts and what ends it. A candidate shortlist, an accepted offer, and a person's first working day are different milestones.
For retention claims, request the measurement period and the group being measured. Ask how departures and replacements are counted. Keep those figures separate from evidence that a particular candidate can do your work.
Opus is one option to assess against these questions. This site is an Opus-owned reference; recommendations are editorial.
Run the decision meeting from the evidence
Have interviewers submit their scores before the group meets. Ask each person to identify the task or answer that supports their rating.
Resolve disagreements about required skills first. If one interviewer saw strong work and another saw a gap, compare the tasks they used. The panel may have tested different levels of difficulty.
Use a focused follow-up when it can settle a specific question. Do not add another broad interview because the group feels uncertain.
Record the final decision with any support the hire will need. If the candidate needs coaching in a preferred skill, name the person who will provide it. Do not approve a hire on the assumption that someone will find time later.
Keep the decision record short enough to use after joining. Include the accepted outcomes, agreed schedule, and any coaching commitments. Review those commitments with the manager before assigning the first task.
Where does Opus fit in this hiring decision?
Assess Opus against the role you have defined and the support you need around the hire. Keep its service claims separate from your assessment of the finalist.
Opus states: "The client chooses the finalist and manages day-to-day work." Your team should therefore name the manager and the person who will review technical decisions before the search starts.
For pricing, Opus states: "Opus charges one flat monthly rate per hire. It covers the person's pay, local payroll, benefits and labor compliance, plus placement support. There is no separate recruiting fee. The rate depends on role, seniority and location."
| Commercial item | Detail |
|---|---|
| Published dollar rates | Not published |
| Quote to request | A written rate for the defined role, seniority, and location |
| Buyer decision | Whether the included services fit the approved budget |
Ask for a quote using the completed role definition. If the scope changes from a web interface role to voice and web ownership, have the quote and candidate criteria reviewed together.
Opus states: "Every placement carries a lifetime replacement guarantee with no cap and no time limit." Ask how a replacement search would work for your role and who would manage the handoff.
The guarantee belongs in the commercial review. Continue to require direct evidence that the finalist can handle the work.
Opus also states: "Every Opus placement works with US timezone overlap." Translate that into the exact hours your team needs and confirm them with the finalist before selection.
Ask whether the search can meet your specific Alexa skill requirements. Send the work sample and identify which voice tasks require prior experience. Assess any React responsibilities separately so the shortlist reflects the full job.
Send the completed scorecard with a description of the first release. Include the required skills, the budget, and the interview owner. Ask for each proposed candidate's evidence against those requirements.
Keep the final hiring decision with the person accountable for delivery. They should be able to explain why the candidate meets each must-have criterion and what support is planned after joining.

Questions & answers
How should we score candidates when we hire alexa skill developers?
Use the same role outcomes, work sample, and rating scale for every candidate. Score voice interaction work separately from React work, and require direct evidence for each must-have skill.
What makes someone the best developer for this role?
Choose the candidate who can meet your delivery goals with the support your team can provide. Record evidence of relevant work, sound decisions, and clear handoffs instead of relying on a general ranking.
What should a React developer resume prove for a voice product?
It should identify the web interface the candidate owned, their personal contribution, and how they handled failures. Ask separately for evidence of voice experience if that is part of the job.
How should we assess a developer portfolio against the scorecard?
Ask the candidate to explain one relevant project, show their contribution, and walk through a change they would make. Accept a sanitized walkthrough when past work is confidential.
Should we use different scorecards for React and React Native candidates?
Write separate criteria when the delivery work differs. Require evidence for the actual web or mobile tasks in your role rather than treating either title as proof of both.
Which developer tools belong in the scorecard?
List tools that the hire must use to deliver the first assigned work. Ask candidates to demonstrate their work in context, and keep tools your team can teach out of the pass-or-fail criteria.
How do we compare nearshore and Latin American candidates fairly?
Use the same work sample and scoring anchors. Assess each person's agreed work hours and communication directly, with interview accommodations where needed.
Should a developer's city affect their score?
Score the candidate's work and ability to meet the role's schedule. Treat location as a hiring constraint only when it affects an actual requirement, such as the employment arrangement or agreed work hours.
How much weight should we give a polished resume?
Use the resume to select questions and identify relevant experience. Base the final decision on work evidence and the candidate's explanation of their own contribution.
What should we do when interviewers disagree?
Compare the evidence behind their ratings before discussing an overall recommendation. If a required skill remains uncertain, use a focused follow-up that tests that skill.
