The interview will continue on January 18th

Three bytedance

It’s next to renmin University subway station, above the China Aviation Building. It feels so fucking rich to see your own building in the headlines. After entering the environment is very good standard Internet atmosphere, until 10:30 AM, the little sister at the front desk finally arrived. Then he took the front interview questions into a small room and began to work on them. To be honest, the headline pen-based exam is the most comprehensive pen-based exam I have ever done. Now my memory is a little hazy. I didn’t remember them then, but I can probably remember them now.

Pen test

  • What is HTTP/HTTPS /http2? What’s the difference between them?
  • Rem mobile layout scheme
  • Write the attributes and functions of the META tags in HTML
  • Front-end native scheme design
  • What is Shallow Clone? Write about the
  • A regular expression of javascript programming problems

I’ve forgotten a lot of topics, but you really need to prepare for the headline interview or you’re going to get beat up. Prepare for basics, computer networks, algorithms, front-end solutions, etc. It was very detailed.

Side – Front end leader

  • The front leader is a master from Beijing University of Posts and Postal Services. All the questions are asked by resume and pen questions, but they are not always carefully guided, pointing out some details to guide you to answer. This is the most comfortable I’ve been since the interview. Although I am very good at cooking, I am not good at many questions. Because he asked too many questions, had a great conversation, and bought me dinner at toutiao’s cafeteria. (ps)
  • Specific questions
    • XSS and CRSF
    • Vue routing, vUE bidirectional binding implementation
    • Several implementations across domains, what is JSONP? Cors is what?
    • Regular expression implementation
    • Depth Clone understands
    • Prototype chains and closures
    • project

2 – the CTO

In the second interview in the afternoon, a middle-aged uncle asked a specific question about the project of sina’s commercial advertising technology department. I did not give a good answer about the specific technology and implementation process. I also asked about my plans and requirements for the company. And then feel already gg. And then the CTO saw me off after the interview. ah

Ps: Toutiao basic 10 9 6, overtime pay, including meals. Work starts at half past ten
