I hope I'm posting this in the right section.
In one of our department, they are hiring candidates based on their chemical engineering knowledge.
Recently, we've noticed a lot of the interviews didn't go very well, as the screening was inappropriate.
While going over the curriculum with my subordinates, I realized that the focus was put too strongly on generic engineering knowledge and questions, that didn't quite pertain to the chemical engineering field.
So my question is, what kind of questions would be most pertinent to ask candidates. The position is mainly requiring environmental engineering knowledge.
Again I'm sorry if this is too vague, I'm just looking to get more information as I'm not an engineer myself. Our company operates in the South of France.
