Depends on your advisor, but in general, a good place to be a grad student - Graduate Student Caltech (California) Employee Review

You get to interact with many smart people

Dining halls should be better

I really like the people I work with. Managers promote psychological safety and follow through with their commitments . My direct managers are interested in my growth and professional development. There are a lot of affinity groups to connect with. Overall a great community to be a part of. Caltech has good benefits and even mental health counseling available for staff.

Because the campus is lightly administered/decentralized, policies can vary a lot by department, which can make things really confusing for the initial period. However, if you’re open to talking to others and making connections, it can go a long way in helping you figure out how things work on campus. Another negative is that departmental culture can vary. Working as an admin in one department may be much more difficult than in another department.
