Many common growing pains at any 300 person tech startup, attrition/turn over, changing roadmaps, etc.
Recent, painful layoffs that cut deep (30%) to preserve the company's financial health. However, if I were looking at a potential job at Metromile, I wouldn't let the recent negative reviews (especially the spicy, lay-off related ones) dissuade me from pursuing an initial conversation or two at least before deciding for myself.
