GLG Event Content Manager interview questions

I've applied online, and received a call from GLG APAC recruting team the next day. The lady is very nice, she has asked me about my previous working experiences, and also introduced GLG's business model to me, even with an example. One week later, she's called me again and arranged a telephonic interview with HK office. The lady at HK office is also really really nice, I've showed her several event cases that I've involved in before. Unfortunately, I've been rejected because they are looking for someone with more advanced English skills. In general, I do appreciate the interview at GLG and also realize my shortage in language.
