Wigglepods interview questions

The usual questions — introduce yourself, your experience etc. But one very important thing to take note, they mentioned during the interview that there is an annual $50 joining / licensing fee (not sure if it’s only for part timers or for full timers as well) that you have to pay if they employ you and you accept the job. Sounds pretty scam like to me. Have worked with other enrichment companies and have never heard of such fees.
