When an interviewer poses this question, he/she may be attempting to assess how well you would integrate into the work environment. However, they will likely expect your answer to include a description that applies to or embodies the atmosphere of their workplace. Common terms that can be used to describe such environments include “professional” or “casual,” “open” or “private,” and “fast-paced” or “relaxed,” among others. It may also help to look into how other similar work environments are described, so that you can use comparable terminology. Avoid superficial and general descriptions, and be ready to justify your reasoning well.
