Self-introduction, not far Keba back!

The interviewer may be positively engaged in the work, and then to interview.

If artificial intelligence? Small degree, small love do not? Why you?

Asked the interviewer

Get out more interviews, not afraid of failure

Departure proved a must (not simultaneously in both companies)

On a company, it is best to be found, eye in the sky check, check ..

Personal evaluation: Do not stereotyped (cheerful, good at work), who can write

project:

• Introduction:

  Operation and maintenance for the liberation of the students, allowing developers to directly test or code to be released, can also be based on tag issued by the git branch + commit information, you can also update the file directly, all publishers are based on the gray release

  Allowing operation and maintenance of colleagues, without logging into a remote machine can execute the commands to customize Scheduled Tasks, etc.

• Features

  • Operation and maintenance for the liberation of the students, allowing developers to directly test or code to be released, can also be based on tag issued by the git branch + commit information, you can also update the file directly, all publishers are based on the gray release
  • Use ansible api directly on the remote host batch management, custom Scheduled Tasks
  • Use celery code released after completion of asynchronous notification developers and testers to test the code online

• Technology stack:

  • django、ansible、celery、pygit、openpyxl、mysql、ztree、jbox、scojs、bootstrap

• Project question:

  • Word on what the gray release

  • Celery is said about how to use? What are the function can be achieved?

  • ansible command what you are?

  • ansible api version is how much? 2 version, the version 2 of all the ad-hoc performed is converted into playbook

  • The project features?

  • Used in the project is modelform? Submission is from or ajax?

  • Whether the project has been on-line? What about traffic? Probably about 20 times the code is updated daily

  • Table Structure? Relationships between tables?

    • user table
    • Host Table
    • Update table
    • Host Table Updates
    • Command Table
    • Initialization table

  • Why not use jenkins? Compared with jenkins What are the advantages?

    • Support gray release
    • Send e-mail support
    • jenkins If you want a release code, you need to write your own script

  • Gray publish a table can be complicated by withstood it? If you could not carry how to do?

  • How to compile java program?

    The system can directly call the command to execute maven compilation

  • Project encountered any problems? How to solve?

    • ansible api

Resume writing:

• Operation and maintenance is recommended to write two development projects (cmdb, code release, the ticket system)
• The most familiar with the project to write first
• Not majors in college, like an entry point
• Do not quit too often (not more than three 5-year work)
• Provident funds, social security
• Do not go abroad
• Spinach gambling sites
• Clear logic
• Do not project span is too large
• Self introduction
• Do not cold field
• Project to a logical
