"There is no official maternity leave policy in the US. As I understand it, the leave is treated as sick time and/or short-term disability. Time off is looked down upon and while I don't think you will be "punished" for taking time off, you will certainly stunt your advancement and bonus. There is a lack of women in leadership roles here, but I believe that is an artifact of the lack of women in engineering in general and not a sign of something lacking within the organization. Your experiences here will depend greatly on which practice you are in and who your supervisor is. Base your decisions entirely on the group you will be spending most of your time with."
