Hello everyone, many friends have left messages to me recently, saying that this year's interview is too complicated, and I don't know where to start!
Whether it is job-hopping, salary increase, or learning improvement! Set yourself a small goal first, and then work hard towards the goal and you're done! In order to save time for everyone, I specially contributed the interview materials summarized by the architects in the circle. The content is very comprehensive and can really be supplemented. I hope everyone can get the ideal salary and offer!
Friends who are preparing for the interview must make a review plan according to their own situation! In addition, you'd better take a self-test from time to time and ask yourself some common interview questions. Due to space reasons, only part of the content is shown here, and the original document is at the end of the article
