If you are a women do not act as if you know anything- it makes the men uncomfortable. Just know all your experience is null and void. You are - regardless of experience and job level - a task doer. Every opinion will be challenged, all experiences undermined and belittled. You will not be assigned jobs or given opportunities commensurate to you position or grade. That will be saved for the men regardless of theirs. You may pull data for them. If you are a male, feel free to take over interdepartmental meetings spewing opinions despite having absolutely no experience. Women are expected to work overtime without recognition. The women in management join in with this culture, look the other way, and do not support professional women. If you’re a women with any experience- run away.
