communication skill最重要。就是遇到困难怎么办,你是怎么解决个人分歧的,时间 管理怎么做的。 Python: numpy, pandas, keras/tensorflow 统计学,线性代数:linear regression, logistic regression, bias-variance tradeoff,regularization,vectorization. brain teaser: 就是类似一个卡车能装多少个高尔夫球的问题 business problem: 你去的公司是干啥的,你有啥实质性建议。 除非你真是CS毕业,或者leetcode刷过三遍,否则考coding的就放弃吧。
