In my time there, Truecar never really had a strong tech and/or product leader. It's currently being run by inexperienced acquihires from a smaller, less-relevant company that was going under. Unfortunately their poor decision making and lack of experience has painfully shown in a record number of people leaving.
Record, numbers. I know you see/hear this a lot on Glassdoor for various companies with poor cultures, but in my entire career I have never seen such a voluntary exodus of talent relative to the size of the department/company.
There's a severe... severe... severe... lack of consideration to diversity within management. Everyone is white, and everyone is within this inner circle of acquihires. Every... one. It's gotten so obvious, that even the other white people have been vocally uncomfortable about the optics of it all. It's evolved to the point where we used to just hopelessly joke about it, because what else can you do?
As written in another review, it's a bad sign when your own HR department is writing scathing reviews about the company. I felt bad because i used to see HR people constantly behind closed-door exit meetings. I can only imagine how that wears you down to always have to bear the brunt of the poor leadership.
No mobility in career. Titles at truecar do NOT indicate ability or aptitude. They're essentially awarded to coincide with whatever your pay scale is. I've seen VP's there only have 1 direct report, directors have none.
While the CEO seems to have done a good job for what he was hired for and has generally received good ratings, at this point the lack of intervention to help fix the culture and leader issues for the other c-levels has to be factored into that opinion.
