Help them temper their expectations. Many people study programming their entire life and get rejected for the lowest-pay L1/L2 engineering positions open at FAANG. These are not easy jobs to land (even in the AI age) and they have to be self-motivated to land one of those seats.

Do they want to get into tech because it sounds like it will make a lot of money, or do they want to learn how to code?

If they want to learn how to code... honestly there is infinite resource on the Internet: books, videos, tutorials, games, ... It's all about finding what works for oneself, and spend enough time and effort studying.

It's like learning an instrument or a new language: it's not about "finding the good book", it's about spending a lot of effort learning.
