One resource I always wanted to have was how does one figure out the responsibilities for a new role that one is interviewing for and is advertised as mid level: 1. Writing, reading, reviewing software most of the time. 2. Some amount of planning on medium sized projects(2 engineers) you are handed over. You can thus iterate on new small(ish) features pretty easily. Like assuming a team of ~5 engineers, how does one go about quizzing the interviewer about different aspects of the role based on prior experience?
