Question:
I have client whose son is in 2nd year of degree college. He has asked me to give him a 2 month internship in coding.
He has no knowledge of programming. Knows basic c, c++.

What tasks can we five him for 2 months to learn programming.

I would decline the offer.

For you, it will only be a waste of time.

If you don't have an internship program setup, within the company, it's an easy hard no imo. Plus nepotism reasons

Most important question. Is the internship unpaid and how much do you need that customers money?

Its not paid, i am supposed to guide him and give tasks to him to develop his skills

Give him some classic tasks to learn programming. Like a Roman numerals converter. And after that something more complex like Conway's Game of Life. The I/O system should be the console for simplicity.

This sounds like a huge conflict of interest. What happens if you find out he is a total shit and you have to fire him?

He should have to go through the interview process.

Go through onboarding, give him tasks to learn your tech stack; you can have him complete online tutorials. He doesn’t have to solve any business problems, but try to give him something to work on that familiarizes him with your environment and workflows. The idea is that he would be a prime candidate for an entry level position later.

Did you all read that he has zero knowledge in programming.

Question is : what does he study ?

Does he like programming ? If by now he didn't program something in his spare time, I have big doubts.

Again, you will only waste your own time and money if he has no interest in it.

@Grumm he is studying chemical engineering

He has no knowledge of programming but knows 3 languages? Eh?
