Meta Hardware Validation Engineer interview questions

Initial recruiter called about 2 months after applying for position on website. We had a short 15 min phone interview after which I was setup for a phone interview with the hiring manager. Unfortunately, there was a language barrier issue. Many of the questions I couldn't answer because I didn't know what the question was rather than the question being difficult. I work in networking hardware and when I was asked "was is ART?" I had no clue how ART relates to networking hardware. After getting off the phone I realized the question probably was "was is ARP?" Most of the questions were like this. The interviewer also cut off the interview prematurely as I was trying to get him to repeat one of the questions. I felt like I didn't get a fair shake, but flushing out these issues ahead of time with the person that is going to be your boss I guess isn't the worst thing.
