电面刚完，就做了一个大概15分钟ppt的presentation，但是电话质量超差，基本没听清，觉得肯定没戏了，郁闷至极，然后给他回了封信
Thank you for your telephone interview, but I can not hear your voice very clearly about what you have said due to the terrible quality of telephone, would you please give me another telephone interview. I‘m really sorry for inconvenience
过了两个小时以后，外导给我回了邮件
thank you for the interview. I think we have got a good understanding of your work during the interview. Your slides were very good. We will tell you our decision about the research position within the next week.

现在再次面试机会也不给我了···哎 请高手支招
怎么回信呢 ··
