Pros
You're surrounded by very intelligent people who know their stuff. They value amition and intelligence. They feed you a lot, which is nice.
Cons
Came into a new role and was expected to jump into work with little to no training and build expertise on things even my seniors did not know. Other employees were rude, dismissive and outright nasty to questions. Did not get to work with anyone closely and with long time staffers staying in their lane no one reached out to give direction for a new role. Expectations for my role were unclear and never communicated outright. I did ask what a typical 9-5 would look like during the interview process and never got a straight answer, which was a mistake on my part, but the onus is on the employer to give new hires direction and ensure they are fulfilling a role. A lot of training was "judgement calls'' but when new hires start they will not know the judgements they should be looking out for. Avoid!
