People at WeWork Say

This information was sourced from reviews originally posted on Glassdoor.

You get the benefits of being at a large company while working in a startup-like tech environment. All of WeWork's technology infrastructure is being build from the ground up, so there's never of shortage of interesting and impactful projects to work on. The culture within technology itself is very fast-paced and open, and everyone is extremely helpful and willing to get to know you. The larger company itself is a bit culty and I don't fully align with all of WeWork's initiatives sometimes. The culture can feel a bit pretentious and "fake woke" at times, if you know what I mean.

The pros are vastly outweighed by the cons. The cult worship of the CEO and VPs, Overly long hours, The weird pervasive idea that they are making the world a better place and their company is a social cause, WeWork is just a glorified real estate company catering to the hip and gullible crowd. They are doing nothing innovative and not changing the world for the better like they believe.

A bit different than most tech companies, if you're into product it's better here since you're very close to the users and you sometimes one of the users. Very talented people that you can learn from - Versatile work, there is all kind of systems- web, mobile, server, data-oriented. It's like many startups under one roof. Great work life balance and managment put emphasis on individual's growth. The growth is so fast (sometimes too fast) and it's sometimes hard to follow what happens. There're times it feels like chaos.

WeWork's mission is to build a more caring, connected world, save the planet, and elevate consciousness. They put their money where their mouth is. Management's heart is in the right place, seem like they learn from their mistakes and take feedback. Keep it up, keep listening to the inspiring mission-driven founders, and keep listening and communicating with the whole team as changes occur, we'll take care of the rest.
