Pros

Amazing culture, some of the brightest people I have ever worked with and great vision for growth.

Cons

Processes are still being ironed out and there are the normal growing pains of a start-up moving out of its initial phases.

Pros

Such an amazing team - everyone shows great empathy, courtesy and caring towards each other. Everyone gives 100% effort and is striving and working together to make the company the best it can be. There's still a sense of fun and humor throughout. The office and perks are pretty slick too!

Cons

Some minor growing pains, as to be expected with any start-up growing at this rate. Nothing particular of note for me though.

Pros

-Strong core values -Inspiring leadership -Employees (at least on my team) are constantly finding new ways to be more efficient -Work/life balance is encouraged -Incredibly genuine people -Lots of opportunity for growth -Great benefits and perks

Cons

Startup environment and lots of processes are still being iterated on. Which I think can be both a pro and a con depending on if you thrive in startup environments or like working for companies with more structure.
