First, is high levels of stress and fast pace, which are ever increasing. It's not sustainable.
Click-y management. It's sort of a spoiled boys club (despite few women among them). Recent promotions and hires only supported "like hires like" rule: no diversity at all.
Very few vacation days (15 days and mandatory shutdown).
A lot of lip service: during all hands HR has brought an issue of bad Glassdoor reviews, but didn't show any care to address the issues.
Ever-constricting review cycle, open office plan and agile. All the tooling to make your workspace as painful as it gets. Managers can slack off-hours.
The work you do drastically changes quarter to quarter, no consistency. It is fully determined by management, you have no say - engineers are pawns in their game. Engineers are considered a disposable commodity and not appreciated.
Lack of empathy from leadership. CEO's quote highlights the hypocrisy pretty well: "one cannot achieve great things with mediocre effort" and then explicitly says that not everybody is suited to work here. Here goes "inclusive" workspace!
