Pamela Fox is one of my (Zoe’s) Career Idols and among other things she has worked at Google, Coursera, and is the creator of the Khan Academy CS curriculum. For me, hearing that even people who are very successful get stressed out by interviews helped me feel better, if that might help you I recommend reading her blog post.
