Some people working have abandoned all pretense of work/life balance. It is unclear to me if this is by choice or not. Care must be taken to maintain balance, but it is possible.
There is an older technology stack that is essentially on life support. I cannot imagine this is exciting or engaging to work with. However, this is quarantined to only one team.
Company has a horrible reputation for overbearing middle managers, terrible turnover, and excessive workplace politics. This is by and large no longer accurate after (several) coups of management, but has still left a vacancy of talent in some areas of the company.
There is a maddening reliance on outsourced labor. This egregious need for short-term productivity will almost certainly result in some long-term code health and maintenance issues.
Work place advancement seems pretty stagnant, even when vacancies arise for positions that could be staffed internally. This appears better for non-developers, for what it's worth.
You are largely expected to be intrinsically motivated to work and improve. Do not expect regular reviews telling you what have done well or poorly this week/quarter/year, or clear goals or assignments needed to earn advancement. This is the other end of the "no middle managers" stick.
Despite what some other reviewers have said, dates are extremely important. Commitments are very often made to external companies, through contracts, and must be met. The VP of business operations is a self-described "dates person", and wears the description correctly and proudly. This is the other end of the "teams are given wide berth" stick.
Unappealing, loud, and bright open office plan. Do not expect to work without sound-canceling headphones; I've had difficulties talking to people right next to me due to the sound, from time to time. Some people have gotten migraines or headaches from the brightness of the lights and intensity of their neighbors.
New fingerprint door scanners are the most infuriating piece of technology I've had to work with in my entire life. The only upside is they are so loud and annoying when they reject you that other people will often come up to let you in so that they can continue working without the interruptions to their work.
