Pros
Individual contributors are by-and-large great people to work with, kind, and highly intelligent.
Nice office amenities like paid lunch, games, snacks, etc.
Cons
Management is incredibly toxic, incompetent and obsessed with micromanagement. Any project that the CEO doesn't personally greenlight ends up dead in the water within a matter of weeks, even if everyone in engineering or other teams unanimously agrees the project is worthwhile.
Draconian work from home policy - 5 days a week in office mandatory and management can and will enforce a surveillance state-like audit of your days in office then use it to retroactively punish you if management needs to scapegoat an IC for their fumbling of (yet another) project.
C Suite continues to focus on making new products instead of refining existing products that still have an immense amount of technical debt to resolve.
Unless you negotiate aggressively, you will be significantly underpaid at HPR compared to market rate, especially for SWEs. The company's previously good retention rate has been spiraling downward over the last couple years as people get sick of dealing with all the bs and jump ship for a better salary and less micromanagement.
Management encourages a culture where engineers end up working far more than 40 hours a week for no additional pay. People working (unpaid) over the weekends is normalized.
Management is constantly advertising completely falsified metrics to clients such as latency and network throughput/messages processed per second. Everyone that does client facing work is told explicitly to maintain these falsifications.
Management and HR regularly demonstrate abhorrently ableist, sexist, and homophobic/transphobic behavior. Management has illegally misled individuals requesting medical leave and pressured them to not take leave.
Multiple instances of employees being laughed at to their face by management when requesting reasonable salary increases.
Multiple instances of management being so derisive and cruelly critical of people's work that they have made people cry in/following meetings.
