The MongoDB Summer '18 Intern Series: the Node Driver, Inside and Out is about Rebecca Weinberger's internship experience at MongoDB where she worked on the Node Driver team. She joined MongoDB as a Summer '18 intern but had previously used the Node Driver in a web development competition during her sophomore year at MIT. Rebecca was interested in computer science due to her older brother studying it, and her experience with the Node Driver sparked her passion for building web apps. At MongoDB, she worked on projects such as improving deprecation warnings and running tests on BSON libraries in the browser. Her experience helped her gain a deeper understanding of the Node Driver's impact on millions of users and its widespread use in various industries, including sports and airline travel.
