This January decided to resign naked, who could not have imagined the development of things become so! The arrival of the epidemic made my poor situation worse

Has been maintained until about the beginning of April, just began to formally look for a job, the process is not simple! Although I think it should be easy to find a suitable job, I often end up bowing to the word “suitable”!

The following is my experience summary of several well-known enterprises interviewed in April and May, “going forward” to pour, “succeeding” refueling!

Byte, Tencent, Didi!

Byte:

Nervous of missing the interview, I sat down at my computer desk early. The interviewer was a little late, so she invited me to a video interview, and it finally started. The face is a handsome brother, a simple greeting, into the self-introduction of the link. Because self-introduction I have been familiar with several times, the effect of self-introduction seems to be good.

At first, I asked for details of my project experience and self-introduction. Since the project experience was really something I had experienced personally, and I usually made a summary when the project was finished, I was able to give a clear answer. Personally, I don’t know what the interviewer thinks, but maybe it’s a situation where I just watch you play dumb.

Without further ado:

  • How much do you understand about Vue
  • In terms of CSS2 and CSS3, I’ll write vertically centered and horizontally centered
  • How do you know about computer networks
  • Describe the seven layers of a computer network
  • What is the difference between TCP and UDP
  • Which layer of the computer network do TCP and UDP belong to
  • What is the HTTPS
  • This section describes several common status codes
  • What is a closure
  • What is NaN, and what does typeof print
  • Js implicit conversion and explicit conversion
  • How to solve cross-domain problems

  • Use JS to determine whether a variable is an integer function
  • What are processes and threads
  • What is a deadlock
  • What is Left Join, Right Join, Inner Join
  • How do I write quicksort in JS

It took about two hours, but finally the little brother said, “I don’t have any problems!”

At that time for their own answer itself is not too satisfied, so the basic know has been suspended
