Maximus Solutions interview questions

The interview was by phone. Everything went well, and I was even happy. a couple of days later on Monday, I received an invitation for another call, of course I thought it was the second interview. But they told me about a test task (a five-page presentation for a client). I wouldn't do this job for free.... I've been freelancing for over three years and I have that experience. No name companies... But the interesting thing is that they never sent me anything!
