Reddit Content Moderator interview questions

Did the first rounds of the interview and everything went fine until the last stage, which was not even supposed to be an interview but a '15 minutes meeting for introduction with manager'. Interviews were based on situational and behavioral questions 'tell me about a time you improved something, you failed, etc'. I managed to pass those interviews and it was supposed to be it. Then, the manager decided to have a 15 minutes 'introduction' last call with the candidates just to know them a bit more. During this short video meeting (due to corona virus), my internet connection broke up but we reconnected in a matter of 2 or 3 minutes. He then said to start all over again with the questions, time ran out and I didn't have proper time to answer the questions and I got rejected. The feedback was that I didn't explained my background well enough. SERIOUSLY?
