Contract hiring runs on a different clock. A team needs someone productive in two weeks, for six months, on a defined piece of work: a data migration, a product launch, a backlog of audits. The full employee loop is too slow and tests the wrong things, such as long-term growth and culture fit. But a quick chat and a rate negotiation leaves you paying a premium for someone who cannot do the work. Contract roles also carry a risk employee hiring does not: how you structure and describe the engagement, starting in the interview, is evidence of whether the person is really an independent contractor. This guide gives hiring managers a short loop for contract and contract-to-hire roles, with classification cautions and a conversion plan.

The first call, including W-2, 1099 and corp-to-corp terms, rate and end dates, is in IT contractor screening questions. For freelancers on project work, see how to interview a freelancer.

Three kinds of contract worker

ArrangementWho employs themWhat it means for the interview
W-2 contractor through a staffing agencyThe agency, as employer of recordYou interview and select; the agency handles employment. Joint employer questions can arise; see joint employer liability.
Independent contractor (1099)Nobody; they run their own businessInterview on outcomes and scope, not on how they will work day to day.
Corp-to-corpThe worker's own company or a vendorYou contract with a business; confirm who the worker is and their right to represent.

The whole loop fits into three to five business days. Good contractors are often choosing between offers that week.

Stage 1: the screen (20 minutes)

  • "This is a [W-2 through agency / 1099 / corp-to-corp] engagement for [term] at [rate range]. Does that work?" Settle the arrangement before anything else.
  • "When does your current contract end, and could it be extended?" Listen for: a firm date and honesty about extensions.
  • "Are you working on, or interviewing for, anything that would overlap these hours?" Overlap is not automatically a problem for an independent business, but you need to know if the engagement depends on fixed availability.

Stage 2: the scope interview (45 minutes)

Share a one-page statement of the work before the call: the outcome, the deliverables, the deadline, the systems involved and the constraints. Then ask:

  1. "Tell me about the most similar engagement you have delivered. What was the scope, what did you personally deliver and how did it end?" Listen for: their deliverables and a clean finish, including documentation and handover.
  2. "Read our scope. What is missing, what is risky and what would you do in the first two weeks?" Listen for: questions about access, data quality and decision makers, and a realistic first milestone.
  3. "Tell me about a contract where the scope changed. How did you handle it?" Listen for: raising it early, in writing, with the cost and time impact.
  4. "How do you hand off work at the end so the team can maintain it?" Listen for: documentation and knowledge transfer as part of the job, not an afterthought.

Stage 3: the deliverable work sample (60 minutes)

Build the exercise from the first real deliverable, scaled down and using invented data. Examples: for a data migration contractor, map fields between two short sample schemas and list the data quality checks; for a contract marketer, draft the launch email sequence outline from a product brief; for a contract accountant, reconcile a small account with planted errors. Keep it unpaid only if it is short and does not produce work you will use; otherwise pay for it.

Score immediate skill (can they do it now, without a ramp-up), accuracy and the quality of their questions. A contractor charges a premium for being productive quickly; the work sample is where you confirm it.

Stage 4: the stakeholder check (20 minutes)

The person who will receive the contractor's work asks how they keep stakeholders informed, how often they report progress, and how they flag a deliverable that is at risk. Score clarity and whether their style fits the reporting the engagement needs.

Scorecard competencies and weights

Example weights for a six-month contract role. Lock yours before the first candidate.

CompetencyOwned byExample weight
Immediate skill on the deliverablesWork sample35%
Relevant delivery historyScope interview; references25%
Scoping judgment and risk spottingScope interview15%
Stakeholder communicationStakeholder check15%
Handoff and documentation habitsScope interview10%
Available for the full termScreenPass/fail gate

The scorecard builder checks that weights add up to 100.

Classification cautions for independent contractors

Checked against the linked primary sources as of October 7, 2026. Not legal advice; get counsel to review any 1099 engagement, and note that state tests can be stricter than federal ones.

  • IRS common-law test. The IRS says all information that provides evidence of the degree of control and independence must be considered, grouped into behavioral control, financial control and the type of relationship. If it is still unclear, the business or the worker can file Form SS-8 for a determination, which the IRS says may take at least six months.
  • Department of Labor test. Under the Fair Labor Standards Act, the department applies an economic reality analysis: whether the worker is in business for themselves or economically dependent on the company. As of October 7, 2026, its rulemaking page says it is no longer applying the 2024 rule in its investigations and shows a proposed rule announced February 26, 2026, with comments closed April 28, 2026; no final rule was shown. Check that page before relying on any summary, including this one.
  • What this means in the interview. Interview an independent contractor about outcomes, deliverables and price. Avoid promising set hours, training them on your methods, describing the role as indefinite, or treating it as a trial for a permanent job unless that is the actual plan, in which case consider a W-2 arrangement through an agency. The agency side of the risk is in worker misclassification for staffing agencies.

Contract-to-hire: plan the conversion on day one

Contract-to-hire works when both sides know the rules from the start. Before the contract begins, write down:

  • The decision date and who decides, such as the hiring manager at week 12 with input from two teammates.
  • The criteria, drawn from the same scorecard competencies, with what a pass looks like in the actual work.
  • Which interview stages remain, if the candidate did a short contract loop rather than the full employee loop. Many teams add the manager and values stages before conversion.
  • The salary range and benefits on conversion, so the conversation is not a surprise.
  • Any conversion fee in the agency agreement; see temp-to-perm conversion fees.

The paperwork at conversion, including a new Form I-9 when the employer changes, is in the contract-to-hire conversion checklist.

The decision rule

  1. Gate: available for the full term, with any overlap disclosed.
  2. Floor: immediate skill at 3 or above. A contractor who needs months of ramp-up defeats the purpose.
  3. Weighted total: in this example, 2.8 or higher on a 1–4 scale is an offer.
  4. Decide within 48 hours of the last stage.

Mistakes that weaken contract loops

  • Running the full employee loop. You lose the candidate and test the wrong things.
  • No work sample. The premium rate is for immediate skill; confirm it.
  • Vague scope. If you cannot write the deliverables on one page, the contractor cannot deliver them.
  • Treating 1099 contractors like employees in the interview. What you promise can become classification evidence.
  • Undefined conversion. Contract-to-hire without criteria turns into an indefinite contract.

Questions people ask

How is interviewing a contractor different from interviewing an employee?

The loop is shorter and centered on a defined scope: can this person deliver these outcomes, in this time, with little ramp-up? You test immediate skill with a work sample tied to the deliverables and check availability and end dates. For independent contractors, the interview should also avoid setting up the kind of control over how the work is done that suggests employment.

Can interviewing an independent contractor affect worker classification?

The interview itself does not decide classification, but what you agree to in it can become evidence. The IRS looks at behavioral control, financial control and the type of relationship, and the Department of Labor looks at economic reality. Setting hours, training on methods or promising an indefinite role points toward employment. As of October 2026; not legal advice.

What standard does the Department of Labor use for independent contractors now?

As of October 7, 2026, the department's rulemaking page says it is no longer applying its 2024 rule in investigations and shows a proposed rule published in February 2026 with comments closed April 28, 2026, but no final rule. Check the page before relying on any summary. State laws can be stricter. Not legal advice.

Should a contract-to-hire candidate go through the full interview loop?

Decide that before the contract starts and tell the candidate. A common approach is a full loop at the start, so conversion depends on performance during the contract, or a short contract loop now and the remaining stages before conversion. Either way, write down the conversion criteria and the timing on day one.
