Yeah I think some actually do genuinely just audition or if they were rejected audition again and then are placed as a housemate. However some go in who were test housemates probably because the producers like them or cannot find anyone else better or some go in because they have an agent or a friend of the producer like Dennis was friendly with Sharon..
At the end of the day.. I think it is worth it to audition. I only got to round 2 but still think it is worth it. Why not give it a shot? But anyways all the auditions are over and done with.. and good luck to the people who have got far!
