Pros
The culture at Whatnot is incredible! People are open and welcoming! The expectations are high, but the benefits reflect this as well! I personally feel validated in my work and get constant shout-outs. I have worked in other places where you get taken for granted very easily. Here people are thankful for the impact you have in your role. It is a start-up, so changes happen fast! It is a very diverse and inclusive workplace. Whatnot emphasizes a can-do-attitude and I would recommend being the kind of person, that wants to get stuff done.
Cons
As it is a start-up, things change quickly and you must be good at adapting! Sometimes, this can be overwhelming, but managers and people on all levels have shown understanding - as this affects the whole company.
