Verz is proof that even the most horrible bosses can build a profitable company.
The company itself is a facade - what you see in pictures do not reflect reality.
Company culture - the company is ruled by ridiculous monetary penalties. What is the point of fining people for being late when everyone has to OT? Being late is the most basic rule, there are penalties for everything ranging from client complaints to not following the least important SOPs.
Feedback to the bosses is impossible. They run by the mindset that "it's not that i don't accept feedback. It's just that my idea is the best idea". if you think that it's harmless to provide feedback, you're dead wrong. Feedback is treated as a form of criticism, and you will be good to be extra careful when the bosses get offended.
Also, if you're joining as a project manager, be wary of certain members of the sales team as sometimes they do not provide a holistic quotation. Clients will complain when they said the sales promised everything, and you are the one to handle all the unhappiness.
If you're joining as a sales, be wary that the bosses have a tendency to deny you what you want (apply for leave) in order to 'spur' you on to meet your targets.
As a realistic example of their character - the bosses found out about Glassdoor reviews some time in Nov 2017, and shortly after many fantastic reviews appeared. I won't claim anything, you can make your own conclusions.
