Frequently Asked Questions

Everything you need
to know before hiring.

What does the 14-day SLA actually mean?
From the discovery call (day 1) to the engineer being onboarded and shipping code (day 14). Typical: shortlist by day 3-5, interviews day 6-10, MSA + access day 11-13, productive by day 14.
How does the replacement guarantee work?
If an engineer isn't a fit, give us 5 business days notice. We send 2-3 replacement profiles within 4 hours. No replacement fee, no penalty. Most teams never need this — but it's there.
What's the typical engagement length?
Most contracts are 6-18 months. Minimum 1 month. No multi-year lock-ins. 30-day notice to end or scale down.
Can we hire the engineer permanently after some months?
Yes. After 12 months on contract, conversion fee is waived. Before 12 months, it's 25% of annual salary. Standard recruiter terms.
What about IP, NDAs, and data security?
Standard MSA assigns all IP to you. NDAs signed before any shortlist. Engineers can sign your own NDAs. ISO 27001 ready. HIPAA / GDPR aware. No code or model weights leave your environment.
Do engineers work in our timezone?
Yes, at least 4-6 hours of daily overlap. India team for EU / US East coverage. EU and LATAM teams for tighter US overlap. We staff to your hours.
How do you vet Mean Stack engineers?
5 steps: 1) Resume + portfolio screen, 2) Technical screen with our senior Mean Stack lead, 3) Live coding test (90 min) with Mean Stack problems, 4) System-design round (60 min) covering modern frameworks/production stacks/Mean Stack pipelines, 5) Culture-fit + reference checks. <4% of applicants pass.
Do you handle Mean Stack Ops and model deployment, or just modeling?
Both. Our Mean Stack engineers are trained on full lifecycle — data prep, training, evaluation, deployment, monitoring, retraining. We can also staff dedicated Mean Stack Ops engineers if you need platform-level work separated from modeling.
