It's a startup that is going through some growing pains right now with COVID and everything else going on in the world. It's also not the type of place for people with "work-life balance" as a top priority. Again, this is a startup and not for everyone. If you want to hop on board the rocketship as it's taking off, you need to be prepared to strap in and hold on tight.
This is not a normal 9-5 job. There are lots of things that will drag you into the late hours and the weekends when you're on a big project. The idea is that you believe in the company and the mission enough that you want to be there in the weeds, pushing things forward and accomplishing goals. If you don't want to put your whole self into your role and your career, then this may not be the place for you.
There's lots of negative things being said about how much the company values employees, etc. There is zero question that the company values their employees incredibly high. The amount of investment they have put into their people is staggering, and they continue to do so even in face of having to lay people off. With programs like Dream Big and other initiatives, they are definitely committed to their people. Not everyone was going to make it through the other side of COVID as I would suspect to be the case for a lot of companies, but I personally am confident that they did the best they could to save as many jobs as they could have.
