中文面的，面试官是鹅厂北美的staff ds\n面试官是组里是做关于游戏的，还问我玩过什么游戏，组里ds product和modelling都做\n先是问了简历上的项目，然后问了一些follow up question. Waral dи,\n之后问了个题\nsay you want to design a email with some links for users in game, how to determine the design of the email say the number of links or the content so that we want to mininze the chance it is detected as promotional email, note that we assume that we cannot get feedbacks from users, it means that we cannot change the design after sending out the emails and see if it is detected as promotional, we want to make sure we have a good design before sending out the actual emails.\n\n路过的可不可以说下这个怎么答，一开始没理解我一直在说发了之后按照user的\nfeedback再改，然后面试官说不能用user的feedback，再发之前就要设计好\n我最后说用historical data predict一下被识别成promotional email的概率，问了gpt感觉他也在乱答\n后面可能时间来不及了，就开始做题了，一道sql，使用windowm function 算\nplayer 的 game played 的按时间日期的cumsum\n下面一题是用Python手写k-means\n面试官说一周给结果，最后一直没理我，无语了，碰到的第二家ghost，没话说，招到人就给我忘了。
