Yesterday, DreamWorks Technology Co. came to the academy to give a lecture, and after the lecture, a written test was conducted. I had another interview today, but I didn't plan to enter, just to gain experience.
But this interview did learn a lot, the interviewer was also very good, patiently explained and pointed out the problems I have now: I only know what it is, but I don't know why.
Indeed, what I've learned now is basically to deal with front-end interviews, so I only know what this thing is, but I don't know the specific implementation principle and why I use this thing. Thinking about it, this is really important. As the interviewer said, doing front-end is not just about art and CSS style design, but also the logic of the entire project, and of course some of the back-end, only in this way can you ask questions to the back-end developers. I have not used many knowledge points in the project. The knowledge we have learned now can only be truly understood by applying it in practice.
Interview content:
Start with the project: introduce your project, then ask questions about the project.
1. How to set permissions for enterprise users and ordinary users.
2. How a certain page is designed.
3. Bootstrap grid
。。。
Other knowledge:
1. What is a closure? Implementation principle? Application scenario?
1. The principle of inheritance in JS
2. The difference between post and get (post, delete, put, get were originally added, deleted, modified and searched?)
3. The way of post (ajax and what)
4. Synchronous and asynchronous
5. I don't know much about Angular.js, because this is the main framework of their company (I only learned vue and React recently, and didn't watch Angular)
6. How does HTML work? When I heard this question, I was still confused. I wanted to ask if I knew Jade (same as HTML, then I asked him what it was and argued with the interviewer about the following HTML and Jade)
7. Do you know coffeeScript, which is also the JS used by their company
In short, after this interview, I know how to learn in the future, three-step method: what, why, how to do it. . .
