Can only recommend if you're starting your career in tech - Manager Zendesk Employee Review

Leadership is weak and incompetent across the board (this isn't an exaggeration) as most are only in their position either because of contacts, politics or simply sticking around for 5+ years as others with actual talent move on to better opportunities. Company lacks clear direction and leadership likes to talk in circles without saying anything at all while dismissing genuine concerns voiced by numerous employees over the last year. Some departments have downright toxic leadership (see current sexual harassment lawsuit); the company may also be engaged in some other questionable activities (can't confirm but there are rumblings). Pay for some employees is well below industry standard and with RSUs gone there's no meaningful way to make up for the lower TC. Top talent has been leaving in droves at all levels and with the company now operating in post PE mode (i.e. cost-cutting) replacing them is unlikely as talented people aren't generally willing to work for low pay. The culture that made the company popular for many years is all but dead and gone now and only getting worse with each passing month.
