The coworkers and thats it.
She needs to have a more organized interview with a recruiter not an intern.
They are patient and empathetic. Try to help the best they can even if they don't know how either.
Have a organized onboarding process, have better distribution of tasks. communicate all tasks in written format in a designated area to avoid confusion. Assign reasonable workload.
The company organization is terrible. CEO is very passive aggressive and gives unreasonable amount of work. Also has no solid onboarding process. She needs to hire more professional people. Divide the tasks accordingly and to create a solid onboarding process.
The CEO makes it clear she doesn't like your work and is very passive aggressive in her communication. She doesn't pay you weekly but at the end of the month and only if she is satisfied with your work(very high standards on day 1 with no onboarding).
