* Product goals are extremely naive, along the lines of "Build a single application that does every cool thing you could ever think of" and "Do it at all once before a customer ever looks at it".
* Waterfall environment. Ridiculous, cumbersome up-front planning strategy that is not collaborative. No customer input. Upper management demands oddly specific features without any customer validation.
* Psuedo-Agile project management. Textbook example of a company walking through the motions of sprints, standups, using JIRA, and planning sessions but having no idea how to generate value from them.
* Mediocre pay. Almost everyone gets hired below their level.
* The complexities of a 200 person team, except it's all insulated R&D and entry level engineers.
* Very disrespectful culture. You will be rewarded primarily for academic prowess and micromanagement. Top-down approach where every meeting is designed to filter out as many people as possible and force decisions upon them. This goes all the way from upper management, where you will regularly hear that executives make decisions without input from directors, to the team level where certain team members get asked to contribute to planning, hiring, etc. and others will never be asked.
