脸瘦家 DE L5 VO后的 Feedback

FB的HR真心赞，长达2页的Feedback，句句言之有据，对我的成长帮助非常大！

VO面试的是DE L5，一共5轮全部通过，但是最后给的综合测评是L4.25的水平，没有达到L5的要求，目前他们也没有L4的岗位，所以建议我稍后继续申请尝试。

SQL：5.5，Coding：3.5，BA/Statistics：4，Big Data/AI：4

为什么说我的Coding是3.5呢？我技术电面过了，VO的题也做对了，人家HR给了详细的解释，大家请看。我服，我真的服，这才是大公司，美帝牛B，比印度亚麻厂好多了。

本人商科MIS背景，做了快7年的BI报表仪表盘，非常熟悉SQL，但是从未接触过和开发过coding。最复杂的设计做过sql sp，event trigger，ETL SSIS package。LC只刷了100道题就去面试了。没说的，继续刷题，干就完了。

FB DE L5 对应的coding水平：

def words_order(text: str, words: list) -> bool:
    word_list = text.split(' ')
    contain_list = [x for x in word_list if x in words]
    
    return contain_list == words

随便举一个例子吧。

题目和我面试时给出的答案，虽然正确 bug free，但是离strong还是有距离，离5级还需要继续努力。FB家DE大部分都是2-3线小厂的SDE或者TOP10名校的硕士。作为2-3线厂的SQL/BI开发和TOP25的硕士，差距还是有的，能拿到面试一路走到VO完全靠之前的7年工作经验弥补不足。

'''
You have a text and a list of words. You need to check if the words in a list appear in the same order as in the given text.

Cases you should expect while solving this challenge:

a word from the list is not in the text - your function should return False;
any word can appear more than once in a text - use only the first one;
two words in the given list are the same - your function should return False;
the condition is case sensitive, which means 'hi' and 'Hi' are two different words;
the text includes only English letters and spaces.
Input: Two arguments. The first one is a given text, the second is a list of words.

Output: A bool.

Example: 

words_order('hi world im here', ['world', 'here']) == True
words_order('hi world im here', ['here', 'world']) == False
