I was the only one out of 620 applicants who failed the final interview in army I applied to the army and completed the physical and written test, I had almost the most points of all, but in the last test, which was the interview, I failed and couldn't pass it, because I couldn't get my voice out. , I was very calm and the interviewers were very kind, and they only asked me about basic things, but I still couldn't say anything and I was the only one out of 620 applicants who failed the final interview test I’m not upset or anything but idk is difficult to live and u can be very easy a homeless
