How long hiring takes
Across the AI training platforms we refer candidates to, the median gap between referral and hire is about 30 days. It varies by platform and role, so treat it as a rough guide for this one.
Interview Prep
Sample questions for a Full-Stack Developer role, written in-house to help you prepare.
How do you decide where a piece of logic belongs, on the frontend or the backend, when either could technically handle it?
I put anything involving trust, validation, or business rules on the backend, since frontend logic can always be bypassed by a direct API call, and I keep the frontend focused on presentation and responsiveness. Duplicating critical logic on both sides just creates two places it can drift out of sync.
What's your approach to designing an API that a frontend team you don't control will consume?
I design around the frontend's actual use cases rather than just mirroring the backend's internal data model, and I version the API from the start so backend changes don't silently break a frontend I'm not there to coordinate with in real time.
How do you debug an issue when you can't tell if it originates in the frontend, the backend, or the data layer?
I check the actual data at each boundary, what the frontend sent, what the backend received, and what the database returned, rather than guessing based on where the symptom is visible. The layer where a bug shows up and the layer where it originates are often different.
How do you balance page load performance against the amount of client-side interactivity a feature needs?
I default to server-rendering the initial content that users need immediately and load interactive pieces progressively, rather than shipping one large client bundle upfront. Interactivity that isn't needed on first paint shouldn't be part of the cost of first paint.
This listing calls for these tools directly. Prep for the technical screen:
What to Expect
Looking at Turing Software Engineering listings we've tracked, contracts in this domain typically run about 8.4 weeks. Actual length varies by project, but this gives you a realistic baseline going in. This listing's 4-week contract is shorter than the typical 8.4-week Turing Software Engineering engagement.
Based on 28 extracted Turing Software Engineering listings.
Why this role
This JavaScript / TypeScript Full-Stack Developer role covers building and evaluating full-stack coding tasks used to test AI models on real JavaScript and TypeScript problems across both frontend and backend layers. Grading spans both layers, so the reviewer needs to catch errors in API design as well as UI logic.

Common questions
How and when does Turing pay contractors?
Monthly, in USD, via Deel, Payoneer, or direct bank transfer. You're engaged as an independent contractor responsible for your own local taxes. Plan your cash flow around a monthly cycle if you're used to weekly payouts elsewhere.
Do I need to be a software engineer to work for Turing?
No, not anymore. Turing built its name matching senior engineers with Silicon Valley companies, but it has since expanded into AGI infrastructure work and now hires non-engineering domain experts, technical writers, and researchers for post-training data annotation and RLHF. A strong analytical background and excellent English matter more than coding ability.
What does task-based AI training work look like?
Practical, hands-on data work: recording short videos, categorizing images, rating text responses, or analyzing data. Tasks are designed to be short and distinct, typically 5 to 60 minutes each.
What does asynchronous AI training work mean in practice?
No set hours, no check-ins, no meetings. You log in when you want, pick up an available task, complete it, and submit; nobody is waiting on you in real time. That's different from remote employment, where you're expected online during business hours. The tradeoff: you're competing with others for available tasks, so an empty queue means there's simply nothing to do until more work is released.
What does Software Engineering work look like for a JavaScript / TypeScript Full-Stack Developer?
Tasks here are scoped to Software Engineering, not generic labeling. As a JavaScript / TypeScript Full-Stack Developer, expect to draw on real domain judgment (evaluating outputs, correcting errors, or providing expert reasoning specific to Software Engineering) rather than following a one-size-fits-all rubric. If you don't have hands-on Software Engineering background, this is likely not the right listing to start with.
What specific skills does this listing call for?
JavaScript, Typescript, Node.js, and Nest.js are named directly in the listing. If you don't have hands-on experience with these, expect the screening process to test for them directly rather than accepting adjacent experience as a substitute.
How many hours per week does this role require?
Based on the listing, this role is scoped at 20–40 hours per week, over roughly a 4-week contract. Treat this as a real commitment expectation, not a loose estimate.
How much does this specific role pay?
The listing doesn't state a rate. The $25–$55/hr shown here is our estimate from the role type and location (see /pay-methodology), so treat it as a rough guide and confirm the actual rate with the platform before committing time.
What happens when I click Apply on this listing?
You'll be taken to Turing's external site to complete your application there. This listing links through a referral, but the process is identical to applying directly; the link just routes you correctly. Create an account on their site and follow their onboarding steps.
Can I apply from outside the United States?
This specific role is open only to people based in the United States. If you are somewhere else, applying is unlikely to lead to an offer even if you pass the assessment, because the restriction is usually about where the work can legally be contracted rather than your skills. Read the full description for any tax-residency or right-to-work caveats before you apply.
Is there an interview?
Yes. Two rounds of interviews (60 min technical + 15 min cultural &, offer discussion)
