Vantaggi
Qumulo has great benefits, aside from not having any sort of 401k matching. Health and dental are generously equipped. Breakroom and snacks are plentiful, if you're in the office. Engineering side of the house is really great and has wonderful leadership and support structures, as well as room to grow. Sales/Marketing/Business Dev are a nightmare.
Svantaggi
HR department is non-existent, so you're pretty much on your own there. Compensation is low to semi-average for most roles, which is a bummer since there's no 401k match. In a span of two years, they had 9 c-suite executive individuals leave their positions. Nine. On top of that, it's exceedingly rare to see anyone that has been with the company longer than 2 years outside of Engineering. Turnover is on an unprecedented scale and it's often sad to see how people are fired with essentially no warning, reasoning, or severance. They recently let go a couple dozen people and did not provide any explanation to the company. There is little to no visibility into what is actually going on with senior leadership and transparency meetings are very often misleading. The "good ole boy club" is very much in effect here and spans across all non-engineering departments. If you have other offers, I'd take them before going to Qumulo.
