I'm very disappointed in my experience working with Steno. I can't answer for others or explain all the 5-star reviews, but I personally would not recommend working for this company. I'm not going to deny, there are some great people and a ton of talent across the board, but these positives were often clouded by managers with huge egos.
Also, be mindful this is a start-up and it's very obvious due to the lack of processes, in addition to, the weekly changes made to the little process that was set in place. It can be hard to keep up even if you're someone that thrives in that kind of environment.
Their People Operations team needs work. If you're wanting any discussion to remain confidential, then don't reach out them them.
Work-life balance is terrible. If you're Eastern Time, be aware you'll be working East coast and West coast hours every day despite what they tell you.
I have a lot more I'd like to say, but it's not even worth it at this point. My advice would be to avoid Steno. An outsider looking in is likely only seeing this company through rose-colored glasses, but as a former employee I can certainly say this is not a 5-star company.
All in all, I don't have any positive things to say about Steno aside from it's a remote working opportunity if that's all you care about.
