Full Stack Engineer to take a paid technical assessment and give feedback

We are an early-stage software startup hiring a Founding Full Stack Engineer. Before we use a technical assessment to screen candidates, we are comparing two assessment platforms, Quala and TalentProof, and we want experienced engineers to take both and tell us honestly which one works better. What you will do: - Complete two timed assessments for the Full Stack Engineer role, as if you were a real candidate: one on the Quala platform and one on the TalentProof platform. We will tell you which to take first when you accept the job (we vary the order between candidates). The links and instructions are shared after you accept. - Complete both within 24 hours of accepting the job. - Answer the feedback questions below in a written message when you submit. Total time is about 3 hours across both assessments and your written feedback. This is a fixed payment of $125 for the full task. Feedback questions (a short answer to each is fine; a 1-5 rating plus one or two sentences works well): For EACH platform (Quala and TalentProof): 1. Ease of use: How easy was it to start, navigate, and submit? Any bugs, confusing screens, or friction? 2. Instructions: How clear were the instructions and expectations? 3. Realism: How closely did the tasks reflect real full stack work (React/TypeScript front end, Node.js or similar back end)? 4. Skill measurement: Did it let you show your real ability? What would it miss, or reward that it should not? 5. Fairness and gameability: Was anything ambiguous, unfair, too easy, too long, or easy to game? 6. Time and pressure: Did the time limit and format feel right? 7. Candidate experience: Would you be comfortable taking this for a real job you wanted? Anything intrusive or off-putting? Overall: 8. Which platform did you prefer: Quala, TalentProof, or no preference? 9. Why? Which factor mattered most: user-friendliness, UI and design, more accurate assessment of your skills, fairness, realism, time, or something else? 10. If you were hiring for this role, which would you trust more to identify strong candidates? 11. What is the one thing you would change about each platform? What we are looking for: - Strong full stack experience (React/TypeScript front end, Node.js or similar back end). - Clear, candid written communication. - Availability to complete both assessments within 24 hours of accepting. We will keep both assessments confidential. Please do not share or reuse them. In your proposal, briefly tell us about your relevant experience.
