Pros
Good cause (mindfulness), and you could work from home sometimes and casual dress was fine, but that's about it.
Cons
Working here was a real low point in my career: I felt that leadership wanted everyone to act like robots and not think for themselves; they intensely micromanage their staff and Board/CEO gets involved in every decision. It was strange to have half the board and CEO on project related calls - just didn't understand the role of the board and governance. Also there's no sense that the 'mindfulness' and mental health they espouse is also for staff - the culture was very anxiety driven and toxic. Management and Board have "favourite" staff members who they invite out to private dinners and drinks, but not others, it's very unprofessional. I had a manager ask me to cc them in on every email I wrote at one point: that's deeply undermining and again, unprofessional. They espouse a happy/friendly/warm/calm exterior but beneath that is a very competitive, toxic culture. And they expect everyone to work 24/7 - I was scolded for not answering an email that came in on the weekend by 10am Monday morning. It's just a weird work culture. I notice they are always advertising roles at the moment: I would warn anyone considering applying that their culture is not what it seems on the surface. It's also a revolving door staff wise (people constantly leaving) and I can see why - many of us stay in touch and we all have similar stories. Beware.
