但是不管怎么说，有些硬技能还是需要的，比如做大数据来说，如果只是了解各种组件的使用，是远远不够的。真正做过大数据研发的肯定是需要写SQL，写各种算子的。对于组件的使用可以通过面试问出来，但SQL和一些编码的硬实力就需要笔试来搞定了。

首先，可以通过下面的网址进入 SQL练习页面，如果无法直接跳转，可以复制到浏览器打开~

SQL在线练习
随后进入网站的SQL练习页面，在SQL练习页分为几个部分。
非技术快速入门
SQL基础强化
SQL必知必会
SQL进阶挑战
SQL大厂面试真题

如果是SQL基础比较差的，可以先查看讲解。这里是一个非常详细的例子，可以了解这部分的主要技术难点。当然如果要系统的学习SQL，推荐的还是看书。比如SQL的经典书籍《SQL必知必会》，获取SQL必知必会电子书，可以关注大数据流动，后台回复 “SQL”。
选择某一个题目进入以后，其实是一个在线编程的页面。在这里可以直接进行sql的练习，我们完全不需要本地再装环境什么的。节约了大量的调试时间。
报什么错也能立即发现。当你把这些题目都练习一遍以后，会发现自己的SQL水平有一个巨大的飞跃。
在 SQL大厂面试真题页面可以看到一些大厂常考的题目，比如某音的一些短视频分析类题目。

公司真题
除了SQL练习以外，也有一些如Python，JS，SHELL，算法等练习题，有需要的同学也可以尝试。
刚刚的SQL练习是属于在线编程的部分，另外推荐的是公司真题和面试题库。
选择公司真题页面，由于我们之前选择了岗位是大数据开发工程师，会帮我们推荐一些大数据开发的真题。毕竟大厂的笔试绝不是SQL那么简单。
