Pros
Take time to look for your people. Under its hard, brick, colonial surface, Harvard hides the gems of fun, diverse, kind, and dedicated work and friend groups. The work culture is wonderful for work-life balance, and I've enjoyed 3 years of taking courses for graduate credit while professionally developing at my day job. My current managers and teammates are incredible people, scholars, artists, and leaders, they are treasures to work with.
Cons
Certain Harvard offices can feel like a trap - watch out for bullies who live long, illustrious tenured careers here. Take the extra time to research a person's personality and reputation beyond their polished web resume. Otherwise, a simple class, meeting, or interview could surprise you for how abusive behaviors are tolerated here.
