Your website is the FACE of your internet radio station. Humans judge faces. Likewise, they’ll judge your station’s website considering how it looks and behaves.
Normal job applications require a well-written resume and cover letter. But if you’re interviewing for a radio position, you may receive a request to send your aircheck. If you're familiar with airchecks or demos, this can sound like a simple request. But it is quite easy to mess up and never get the job.
