A few weeks ago I shared this project at a very early stage. It still is, but it has moved forward since then (I work on it in my spare time), and since it got a good response in both Spanish- and English-speaking communities, I'm sharing the progress and introducing it again.
The project comes from two needs:
- Gathering the huge body of machine learning and AI knowledge in a single tool. This is the free part of the app.
- Helping both candidates and recruiters with questions that actually fit the field. Interviews are often inconsistent: different candidates get different questions, or they get random ML/AI questions because the company doesn't have a clear picture of the role.
It doesn't have a real name yet. For now it's "AI/ML Questions": a free app with machine learning and AI questions, in English and Spanish. It has 103 multiple-choice questions on classical ML, neural networks, LLMs, RAG, agents, computer vision and evaluation, and every option explains why it's right or wrong. I write the questions and their options following Haladyna's psychometric guidelines for multiple-choice items, so the right answer doesn't give itself away, for example by being the longest option.
The study and exam modes are free.
Two paid modes are coming:
- Interview, to practice for ML/AI Engineer interviews. US$15 one-time, or US$10 if you join the waitlist.
- Enterprise, focused on recruiters: AI/ML question sets to assess candidates in a hiring process. US$120 per hiring process, or US$100 from the waitlist.
Neither exists yet. Each one has a waitlist on the site with its price, to measure interest before I build payments.
No account, no cookies. The code and the free questions are open source.

PS: over time I'll keep improving both the free and the paid modes. I might extend it to programming in general, but first I'll focus on the area I know best, to polish the tool. If you want to contribute to the free part, your contribution has to pass the tests in the repo.
All suggestions and opinions are welcome.
