I worked at Johns Hopkins University full-time
Cutting-edge, world-renowned research university with all the accompanying resources (stellar faculty, beautiful campus, nice location, college events and activities). Great salary and benefits including tuition remission.
There's not really a downside.
There's actually no interview in my department... I believe some departments would have some professors talk to you about the post but this is not the case in my department. You just need to submit your resume & wait for their final decisions. My professors recommended me so I automatically became a TA.
