JobsVocate Tip
The mandatory tests are your gate‑pass. Do not rush them. Sigma tests your ability to listen, write correctly without spelling mistakes, and follow annotation guidelines. Before you apply, practice typing in Hausa (if you have a Hausa keyboard, good; if not, use online tools to check spelling). For the English portions, ensure you write clearly – no text‑speak. Also, check your computer meets the technical specs: Windows 10+ or macOS 13+, RAM at least 4GB, working webcam and mic. If you are using a tablet or iOS phone, you will be rejected for audio projects. Finally, Sigma uses AI in its selection process – your transcribed content will be evaluated automatically. Be accurate.

Frequently Asked Questions (FAQ)
Do I need to live in Abuja to apply?
No. The location is listed as Abuja, Nigeria, United States, but the role is fully remote. As long as you are in Nigeria with a stable internet connection, you can apply.
How much does Sigma.AI pay?
The original post does not specify rates. Freelance annotation typically pays per task or per hour (often 3–10 per hour depending on complexity). You will find out during onboarding.
Is this a full‑time job?
No. It is freelance, with tasks available through an online platform. You choose how much or how little to work. No guaranteed minimum hours.
Do I need a degree to apply?
No. Fluency in Hausa and English, plus basic computer skills, are the only requirements. Experience in annotation is preferred but not mandatory.
I have an iOS phone. Can I still apply?
For most tasks (annotation, transcription), a computer is sufficient. For audio‑collection projects specifically, you need an Android phone. If you have only iOS, you may still qualify for non‑audio projects. Apply anyway.
