Tesla goes from one firefighting to another, it's a place that while growing is not "growing up". End of quarter are always nuts, people are asked to perform miracles and of course quality suffers when everything is a fire. They had some serious rethinking of how the organization works lately so a bunch of people that had a lot of power ended up with considerably less of it, and some new faces are ascending rapidly.
I don't work at Tesla, I'm just familiar with the situation through close acquaintances. People are getting REALLY tired of hearing "next quarter will be different and we'll start putting processes in place..."
