Even if you are not changing your job, it is still a good idea to attend at least 1 interview every year. This is to:
Know your current values
Suppose you work at a place for quite a long time, you feel comfortable, which sometimes is not good for you to understand your current values (your advantages and weakness). An interview reviews what you lack and what areas you need to improve on.
Know the latest technology stacks
Technologies evolve quickly, e.g. especially for front-end frameworks that come out every few months. Staying in one place may not give you chances to get hands on these new things. An interview is like a free idea exchange meeting, why not?
Train your interviewing skills
Do you still remember when is your last time to do the IQ puzzles or logics tests? An interview helps you to pick up these, as well as the interviewing/communication skills.
Broaden your horizons
Different companies do different things and do things differently. An interview gives you different ideas, and help broaden your horizons.
Regain your confidence
Feel frustrated at your work? An interview helps you regain your confidence, because you will normally be asked what you currently do in your role and that is the thing you are best familiar with.
很多人认为要换工作才去面试，其实并不然。即使你不打算换工作，你每年也得去面试。这是因为通过面试可以：
让你了解你的优势（价值）和不足
即使你的现在的工作很舒服，你对你现在的工作已经得心应手，去面面试也是个让你再一次了解你价值体现的机会。有时候在一个地方久了，容易变成老油条，出去面试，发现不足，容易正视自己。
让你了解市场行情
计算机技术发展日新月异（比如前端框架技术几乎几个月就冒出一个新的技术），平时在同一公司，特别是做的事情都是一样的，很容易与流行技术脱节。通过面试能了解当下市面上所需要的人才和薪资。
拓展你的思维
不同的公司业务方面不一样，去面试能拓展思维，了解到不同领域，艺多不压身，不是坏事。
锻炼你的面试能力和技巧
我都不记得上次做面试题是啥时候了。假设你的公司下个月倒闭了，那么你是否立马能找到工作？时刻让自己的面试技巧和能力都处在最优状态对你没坏处。
找回你的自信
工作上自信受挫了，对自己能力不自信？那可以去面面试，在交流的过程中找回一些自信。比如面试官很经常问你关于你现在工作的内容而这一点你是非常熟悉的。
