Frequently Asked Questions
Is AI removing entry-level roles?
AI is changing workflows rather than removing the core need for people who frame problems, clean data, and ship reliable pipelines. Teams still hire for those skills because they drive real outcomes.
How do I choose a first project?
Pick a question a team would pay to answer next week. Keep the scope small, ship the result quickly, and iterate. Momentum is more powerful than a perfect plan.
Do I need advanced math to begin?
You need applied statistics and comfort with experimentation. You can start with practical ML and build theory as you progress.
