I am hoping to start a new office job in the next few weeks. I would be remote for the first few months due to COVID. This is a senior level role reporting to the director with a lot of cross-functional interactions with my boss' peers and senior members of their teams. I wouldn't have directs at first, but would probably be recruiting some after the first few months. I'm an introvert and can be mildly socially awkward if I'm not mindful and make an effort. I want to get off on the best possible foot with my new colleagues. Also, it seems that I will be one of the oldest people in the office (almost 50, 10+ years older than the boss).
What casts should I listen to get the best possible start, especially in building workplace relationships?
