比较久之前T家的面试,结果就不共享了,只贡献题目,可能给面Machine Learning方向
的有些帮助。
电面1.
(1)一些统计的问题,二项分布,大数定理,抛硬币做概率转换
(2) (写程序)用stack实现queue
电面2.
(1) Trending tweats的算法设计;tweat topic的提取;
(2)(写程序)输入一个程序源文件,写一个程序去掉所以有的comment
Onsite:
(1). (a)(写程序)两个字符串的最大公共字串
(b (puzzle)game: the interviewee is an oracle of a function "bool f(
int, int, int)", that is, the interviewer can provide three numbers as input
, then the interviewee can give the TRUE/FALSE answer. Play the game and
find the precise definition for the function.
(2). (a) some fundamental concept for machine learning (precision, recall,
ROC curve)
(b)(写程序)爬楼梯的题,valid single-step move is 2^k (always starting
from the first floor). Given a target floor n, output the best strategy to
reach it.
(3). (a) some system design question regarding news feed
(b)(写程序)reservoir sampling
(4). (a) (写程序)coding multiplication of 2 matrix
(b) (写程序)coding multiplication of a list of matrix
(5). (讨论)new feature to Twitter; trending design (again), some related
statistical model; linear regression 101; recursively use 1-feature linear
regression and the complexity discussion.
(6). (讨论)Machine Learning feature engineering for Twitter Ads; formula
and implementation of boost tree machine learning method; how to use
parallel computing to speed up training process; some discussion on
convergence speed.
