Programmers is a site in the Stack Exchange format for asking questions that potentially have single, correct answer.
One example of a question (just looking through some recent ones) of this nature is Why Was Python Written with the GIL? There is an answer to this question - it has to do with optimizations on single threaded programs, and avoiding some other pitfalls of multithreaded natures.
On the other hand:
Hiring people with exact skill is difficult.
So our strategy has been hiring people based on talent and make sure
they are as young as possible. Then we train them.
We can't give them big project straight away. If we do that, we often
end up reprogramming from scratch due to design issues.
I think we should give them debugging jobs or small project jobs.
What other tasks usually such people do?
This is asking for a range of answers - all of them potentially equally correct. There is no single correct answer, or even the possibility of one.
The Stack Exchange format is not set up for discussions or polling of ideas. It just doesn't work well for those cases. Trying to make it work for those compromises the thing it does work really well for - questions that have single correct answer. People come to the Stack Exchange network to find answers - not to discuss problems or see what everyone else has to say on a given topic.
