$100–120/hr

rate as listed

Workload: ~15h/week
Engagement: Project-based
Location: US
Field: STEM and Coding

Participate in a one-time expert interview about how engineering teams serving retail investors evaluate and integrate external API or AI vendors. The work is intended for current in-house engineers or hands-on engineering leaders who have recently helped choose a vendor, not only implemented one.

The interview

This is a single remote conversation lasting 45 to 60 minutes. You will discuss a recent vendor evaluation or integration involving areas such as market data, news, research, identity or AI chat, including how candidates were shortlisted, why one was selected and what affected implementation quality.

What the platform screens for

The screen is likely to ask for verifiable detail about your current in-house role, the retail-investing product you support and your involvement in a vendor decision within the past 12 months or one planned soon. Strong candidates can distinguish their own contribution from the wider team’s work and explain tradeoffs involving documentation, reliability, pricing, security, compliance and vendor support without sharing confidential or proprietary information.

Logistics

The interview is scheduled remotely at a mutually workable time. It is a one-time live commitment rather than an asynchronous project, with no recurring weekly hours stated.

Pay band: $100–120/hr

Interview prep — 10 questions

Matched to what this platform's screening actually measures. Answer each out loud in 60–90 seconds: claim → concrete example → implication.

What it tests: This verifies that you are currently in-house, remain technically close to the work and support a product that reaches retail investors.
A strong answer: State your title, employer type, core engineering responsibilities and the retail customer journey or platform capability your team owns. If you are a lead or manager, clarify how you remain hands-on.
Where people lose it: Candidates lose credibility by describing fintech work broadly without showing that the product serves retail investors or that their current role includes direct engineering involvement.
