True miles....I've spoken to very experienced Engineers on some forums.....majority very helpfull with no ego in explaining facts & going all out to assist a collegue,but a few minority very good engineers but with a very selfish attitude who do not help a collegue but rather give standard two-three words or a sentence of disapproval or ridicule.
The former are people we need in our fraternity.With time spend one knows who the good ones are.
On the topic of command over the language,it is very important else the candidate will struggle as one goes ahead in this field.
