Women in the Workplace

I'm asked askreddit, but I figured you guys might have better advice, from the men's point of view.

I just graduated from a women's college, and am about to enter my first job, which is in the world of corporate finance. Today, I learned that I'm one of only a few women that the company has hired, and women comprise only about 10% of the analysts there.

I want to know what I should expect, and how I can prepare. I'm worried about not being taken seriously, and now, looking at the answers I got on askreddit, having people just constantly judging my appearance instead of my work. What are your experiences with women in the workplace? What advice do you have for me?
