Book excerpt: "For undergraduates in STEMM fields, the experience of working in a lab or other research position has become an increasingly important credential for many career paths. Landing such a position can be difficult, with hundreds of applicants for perhaps a dozen openings in the most competitive cases. But finding a meaningful research experience also involves knowing what to look for and how to present yourself effectively, skills that represent a hidden curriculum for many students. In this book, an expert lab manager and a longtime principal investigator share their secrets for securing these positions, both in summer undergraduate research programs and in labs operating during the academic year. They offer advice on the application and interview processes for undergraduates who often do not know how to prepare appropriately professional emails, cover letters, CVs, and interview responses. They address students in a wide variety of STEMM fields at both research-intensive universities and primarily undergraduate institutions. And they focus on how first-generation college students and those from low-income backgrounds and communities historically underrepresented in science can learn to negotiate the hidden curriculum and claim their place in research settings. This new edition also serves as a companion to the authors' social accounts, including @YouInTheLab and @TheLabMentor, where they offer advice on lab life at many levels"--
