I had high hopes for this company, and sadly it turned out to be the worst job I've ever had. The perk of working with great people isn't one that will last. In my time at the company, I didn't meet one person who genuinely enjoyed their job as a whole. Everyone I met was relatively unhappy.
I left the organization in the last 6 months, and at least five employees that I worked with on a regular basis have since left, with many others looking at the door. Retention is a problem, and those that stay are only there for the stability. If you have children, you'll get a free pass to leave early and execute a bit less. If you don't have children, expect that you'll pick up the slack of the parents when they leave for the day.
Teams are designed to fail. Everyone recognizes this, yet poor structure and bad leadership are topics no one wants to address. Too many employees leave the office at the end of the week feeling overworked and demoralized.
If you think you can openly speak to your manager about any of those issues, think again. It only makes you a target if you're not willing to put a smile on your face and pretend issues don't exist. Management finds a way to justify bad behavior to no end. You can speak with HR but doing so only shines a light on you. Expect your complaints to be filed away, never to see the light of day.
