Crazy micromanagement from the CEO, I have never seen this before and when I tell stories to other colleagues in other companies, they are usually shocked. Management does not take feedback well and only listen to what it wants. Not much interaction with different departments and absolutely no onboarding and training provided. The CEO sends you a huge pdf document written by previous colleagues so you can read and figure it out by yourself. I would say stay here only for the time you need to help make your CV look stronger, but leave as soon as you can. Growth opportunities are also very limited.
