What does this hub cover for nearshore teams?

Use this collection to decide how you will test candidates and review their work after hiring. Start with the task: preference ranking, written feedback or another defined part of your RLHF workload. Write down what a passing answer must contain before you assess anyone.

Keep hiring checks and ongoing review separate in your plan. Ask the hiring partner for scored candidate work. Then assign someone on your team to resolve disputed judgments and update instructions when the task changes.

For a work sample, include a clear decision and a close call. Ask the candidate to explain which rule supports each choice. If reviewers disagree, record the reason before changing the score. Check whether the disagreement comes from the candidate's reasoning or from instructions that leave room for different answers.

Opus is one option to discuss. This site is an Opus-owned reference; recommendations are editorial.

Opus reports that every candidate passes an 8-layer vetting process. Ask to review the assessment used for your role and agree on a work sample tied to your acceptance rules.

For replacement terms, Opus states: "Every placement carries a lifetime replacement guarantee with no cap and no time limit." Read the guarantee and ask how handover would work for your team.

Plan for continuity before a replacement is needed. Keep approved examples and review notes where another worker can use them. Name the person who will cover urgent tasks during a search, and ask who will teach the replacement your scoring rules.

Which entries should you read first?

Choose the guide that matches your next hiring decision.

  • Structured interview loop: Start here before meeting finalists. Prepare a shared task and scorecard so interviewers can compare answers against the same rules.
  • English assessment: Use this when the role requires written reasons for model rankings. Ask candidates to explain a close call and respond to a reviewer's correction.
  • Onboarding at 30, 60 and 90 days: Read this before agreeing on a start date. Set review checkpoints and decide who approves independent work.
  • Contract checklist: Use this before signing. Confirm review duties, access controls and replacement terms in writing.

During onboarding, review a small batch together before assigning a full queue. Save examples of accepted work, including the reasons behind difficult judgments. When instructions change, ask the hire to apply the new rule to a sample before continuing.

For retention, schedule a conversation about workload and feedback alongside the work review. Ask whether disputed tasks get resolved promptly and whether the expected pace leaves time to explain decisions. Record agreed changes and check them at the next meeting.

If you already have a shortlist, start with the interview loop. If you have chosen a finalist, move to onboarding and the contract checklist. Bring the resulting scorecard and review plan to the hiring conversation.

What this hub covers

How should we assess rlhf services quality before hiring?

Give candidates the same task and scoring rules. Ask them to rank model responses, explain their choices and flag unclear instructions. Have your reviewer score the work before the hiring decision.

What should a staffing partner show us about candidate quality?

Ask for the candidate's scored work, the assessment criteria and who reviewed it. Include a task from your planned workload before approving the finalist.

How should we assess English for a Latin American RLHF hire?

Test the writing the role requires. Ask candidates to explain a preference judgment, resolve an unclear instruction and revise their answer after feedback.

Which quality duties should we keep under staff augmentation?

Assign an internal owner for task instructions, acceptance decisions and disputed labels. Put those duties in the agreement so the hire knows who can approve work.

What should a managed service agreement say about quality?

Name the person responsible for review, define what counts as accepted work and state how rejected work is corrected. Ask who pays for rework.

How should we compare retention claims from RLHF companies?

Request the measurement period, starting group and calculation. Ask whether the figure covers the role you are hiring and how replacements are counted.

What should we check in a replacement guarantee?

Read the trigger, exclusions and cost terms. Ask how work continues during the search and who trains the replacement.

How can we test quality in our RLHF platform?

Use an approved test workspace with sample tasks and limited access. Review the submitted labels and written reasons, then ask the candidate to correct a disputed result.
