Interview company overview and interview topics

I. The Fourth normal Form

Company Profile and JD

  • Company profile: big data company, a pile of cattle, the working environment is really good, is far from me on the ground. It should be close to a lot of people.
  • JD: Visual project experience; Browser compatibility; One year experience; , etc.

In fact, JD is very suitable for my needs, and I am also very interested in visualization. All the online comments are quite good. Then I sent in my resume. Also went through the initial screening of HR. I asked for a half-day’s leave again. I still remember it was not easy to insist on going that day when I was a little dizzy.

The interview questions

  • The front leader

    • 1. Introduce yourself, school and program
    • Why did you change your job in half a year
      • This is a question that almost every interviewer in every company asks, because it’s the kind of question they get when they jump ship with too little experience.
      • And here’s what I said for your reference
        • Company development is limited to me (my former company is a relatively large communication company, still in a set of jquery)
        • Expect to have a good platform, such as your company, and then according to the target company to praise the company in line with their expectations and fit their own development direction.
        • Ps: The main thing is to be honest and serious, don’t be careless, interviewers (especially HR) are very important to this question
    • 3. Most satisfying project
      • Sina project introduction
      • The specific construction of the project and the technologies used
    • 4. Problems encountered in the project
      • I talked about CSRF and XSS
      • canvas fingerprint
      • Cross-domain solutions – CORS and JSONP
    • 5. Promotion of function declarations and variable promotion topics
    • 6. Talk about the storage methods of browsers
    • 7. Ask sharp questions about the project, and clearly know that the interviewer is focused on the project
      • Discusses the approach of hiYouth fuzzy search
      • The realization of linkage between specific modules of advertisement landing page tool is discussed
      • Ps: All the resumes involved are their own projects.
    • 8. Classic three-column layout two implementations, handwritten code
    • 9. How to center flex’s features
    • .

  • The interviewer asked some difficult questions and I didn’t answer them very well. Then I asked a few questions about the company’s projects and front end composition, and the interviewer asked me to ask the CTO to interview me later. After waiting for about 10 minutes, he said sorry, CTO was too busy and asked me to go back and wait for the news. Hr will contact you. (Inner OS: REALLY MMP, actually quite want to join this company, the result is this)

  • It turns out that they really don’t pay attention to the interviewer. not a single call from hr. I immediately contacted the next company after I came out of the fourth paradigm to change the time and said that I could have an interview today, but did the next company have time (the two-hour interview time prepared was basically disrupted by this company)?

  • Luckily, I was on the subway heading to my next job when two invited me for an interview. I saw one nearby and went to the interview. And then there’s this one down here
