the first round is with the CEO. He convinces you that you know nothing and you dont deserve the salary you asked for or you are getting. If you are desperate for the job, its a plus point for him. He then asks you to spend your entire day there and do their work so that they can judge you whether you are ok for the job. He will give you tasks that are important for the day and that client wants. he doesnt have employees so this is how he gets work done. you do your best. he asks you to go and then he says if you can join on less salary then you are welcomed. No matter how good work you do.
