Work-life balance - there is no massive workload like in startups 90% of the time. All the standard benefits.

Tons of politics. Often hiring unprofessional and lazy people (at others' expense when it comes to work). People fighting and no respect for each other, while managers don't interfere and don't care. Work with old, ancient technologies from before 2010, everything mostly written in-house – forget getting experience with modern, popular tools. Managers have no problem promising career opportunities without the intent of actually acting on them to keep valuable people from leaving for as long as possible.

Atmosphere of lies – speeches of 'workplace of choice' and 'safe workplace,' while in the background, people are engaged in petty politics. Managers giving speeches on how advanced, cool, and modern the product is, while in fact, in all departments, people work either with limited & buggy in-house frameworks or tech from 2004.

Career opportunities – even if you're a ninja dev, if you don't have connections in the 'original' group that started the place, your chances to get promoted are very slim, to say the least.

You could stop lying to people at interviews and tell them the truth: the tech they will work with will not be modern and cool.

You could care about the workplace atmosphere, not by throwing blank messages and sticking pictures, but by trying to stop abuse, fighting, and politics, and creating a respectful atmosphere like in most other companies out there.
