Do you think that entry-level IT hires should receive training in foundational skills (like decision-making or problem-solving), or would you expect them to be proficient in those skills upon hire?

When hiring, you expect all the skill sets to be commensurate with the position you are filling. With an entry level position, they should of course have a very solid foundation in place to build on, but being proficient usually comes coupled with experience. I would add that any subsequent training, over time, to supplement and reinforce those skills would be a benefit to the individual and to the organization.

I don't necessarily expect entry-level hires to have decision making skills, but I -do- expect them to have problem solving skills, unless they're really really entry-level doing rote tasks that should probably be automated.  Certainly those who have those skills upon starting will do better and get additional responsibilities sooner.

It's always a mix of both, but I recruit for the person as much as their skills. The ideal hire brings new skills into the organisation, a new mindset, diversity that enriches the team around them. At the same time, skills like problem-solving and decision-making aren't just general competencies, but often specific methodologies which require training. 

For entry-level hires, I would expect some basic capacity in skills like problem-solving, critical thinking, and decision-making — after all, those should be cultivated in their education or prior experience (even internships or projects).

I believe that it would be imperative to ascertain basic judgement and analytical skills during the recruitment process. Problem-solving and decision-making are contextual requiring further training once hired; however, an interview and reference checks should validate these base capabilities to ensure an ability to learn.

In terms of proficiency, I would expect a level of competence for the role being filled, with an understanding of the opportunity for further professional development and competency development in the role.
