As an interviewer

I recently interviewed a front end dev. I ask him the following questions. Of course in Mandarin Chinese:

  1. Have you used Vue.js before?
  2. What AJAX library you use? axios? jQuery?
  3. Do you know how to get JSON data, then render it to the web page?
  4. Do you know how to add custom headers like Authorization?
  5. What would you do if you find something on the web page disappears?
    • What if you got CORS Request Blocked?
  6. What would you do if you find the AJAX request fails?
  7. I recently use axios to send a POST request but find that no parameters have been sent in the request. What do you think?
    • My Content-Type is application/x-www-form-urlencoded and I am sure that my parameters are correct.
    • Here's the hint.

I expect this guy know the following issues by these questions:

  1. AJAX call
  2. HTTP requests
  3. How to know where the problem exists
  4. CORS issue, Content-Type in axios issue
  5. How to find help

An issue I really concern but haven't ask is about comments and documents writing: I don't know how to ask such questions. Maybe I can teach him when he truly becomes my office mate.
