preface

The story goes back to September. Affected by the epidemic in Southeast Asia, the business group I worked in was reduced and I was optimized. The number of front-end staff in the group was also reduced from 8 to 2 last year.

Three of them left on their own initiative (two went to Bytedance, one went to Freely), three were optimized (one passed Tencent/Bytedance/Xiapi/Webank, which was to be decided, and one also got the offer of 20K +), and I also settled down and went to Lexin Group (Instile).

The biggest feeling is that education is really important, a deep bleached two small development, bytedance/shrimp/Webank, etc., not even the opportunity to interview (direct feedback “college” at the end of the undergraduate did not give the opportunity to interview). So far, pay tribute to all the previous 22 years Loser, after graduation and his race.

The interview situation

Tencent (hang)/super big factory

  • Virtual list optimization

  • Webpack performance optimization

  • Which loader to use for SVG
    • svg-inline-loader
  • What is the display attribute value of the CSS
    • none/block/inline/inline-block
  • What else is adaptive besides Table and Flex
    • Gird
    • The percentage
  • algorithm

Please refer to leetcodede’s question 415, I did not write it out, and the interviewer did not give the optimal answer, because it is a little low to cycle more than 10,000 times.

Why write this failure of the interview, because I really want to make fun of their very food, and their commodity center colleagues went to Tencent (one front-end, two back-end), and finally met the interviewer is my back-end former colleagues colleagues, the world is so coincidence!

Start with the MacBook Pro

With this MacBook Pro and his race small two deep drift.

MacBook Pro uses apple’s own M1 chip. Programmers are worried about the impact on development, so I personally tested some of the necessary applications for front-end development!

  • Google Chrome works

  • The node is normal

  • Vscode normal

  • Project operation is normal

MacBook Pro smells good! I will not talk about martial virtue!
