Ok no worries. According to the CIC website, they only test and interview people between the ages 18 and 54. If anyone else had/did not have an interview experience, let's hope they share.
I want to also add that my interview experience was long because I traveled a lot in the past and they verified every stamp, passport, VISA i ever possessed. For language assessment, they asked me general questions such as what I do for work and all. I heard from other people that if the CO thinks you're not proficient in either French or English, it can be an issue. Further more, during the application process, you're expected to show proof ( at least proof of completion of secondary school in English or French) that you're proficient in either English or French.
