Was that an engineer, or an intern? Interns often staff labs, but they're usually taught that anything beyond an introductory question warrants seeking out the appropriate experienced engineer and introducing the developer to them. Heck, even real engineers who simply don't have expertise in the area know how to find the right person who does have the appropriate expertise.

Googling or using Stack Overflow to answer someone's question is simply wrong. Even if it was a really basic introductory question.
