I'm currently working full-time at Meta and do not teach courses personally. Instead, I recommend a small set of interview prep courses that I believe are genuinely high quality. Learn more in Who is Joma Tech and Where is Joma Tech.

I've personally taken courses taught by Rituraj, a Meta alumnus and Y Combinator founder, and can confidently recommend his teaching style. The material is practical, well-structured, and focused on real interview outcomes.

Frequently asked questions

Quick answers about courses, discounts, and what I'm up to.

Who is Joma Tech?

Joma Tech is a YouTube channel and brand created by Jonathan Ma (Joma), a software engineer known for tech comedy, career stories, and interview prep content. Read more on the Who is Joma Tech page.

Where is Joma Tech now?

As of August 2026, I'm working full-time at Meta and not teaching courses. See Where is Joma Tech for the full update and what I recommend instead.

Do you still teach courses?

Not right now. Instead I recommend HireCade courses taught by colleagues from Meta and Google. Start with DSA & Interview Prep or Python.

How do I get a course discount?

You can get 20% off HireCade courses by mentioning “Joma Tech” on the interest form. There is no coupon code, HireCade applies it after you submit. Details on the Interview Prep Discounts and Course Discounts pages.

Where can I find remote AI training and data annotation jobs?

Browse them at dataannotationjobs.org/jobs. It aggregates remote data annotation, RLHF trainer, AI trainer, and LLM evaluator roles from Scale AI, Surge AI, Mercor, DataAnnotation, Micro1 and others, with nearly 800 listings refreshed daily and searchable by company, skill, and location.

What is a data annotation or RLHF job?

A data annotator labels text, images, audio, or video so models can learn from it. In 2026 that usually means ranking chatbot answers, writing better responses, or judging whether an AI output is accurate and safe. RLHF is reinforcement learning from human feedback: you compare two model answers, pick the better one, and explain why. Both are listed on dataannotationjobs.org/jobs.

How can I make money while I job hunt?

Remote AI training work is the most realistic option right now. It's contract work, so it fits around interview prep, and the specialist coding, legal, finance, and medical listings post $75 to $125+/hr, well above generalist labeling. Start with the open roles.

Where should I start if I am new?

If you're starting from zero, begin with Python. If you're prepping for coding interviews, go to DSA & Interview Prep. Or browse everything on the home page.
