Different enterprises have different recruitment requirements , Specific can be on the recruitment website to understand

General business Junior java Develop job requirements :

The interviewer will ask basic questions , Will ask questions based on your project , Can ask very shallow also can extend ask very deep , It depends on whether you are a fresh student in the interview , Or packaging 1-2 Years of experience , The difficulty of the interview questions is different

For example, this year's students have no work experience in the interview , A clear point , Ask to say it

If it's packaging 2 The interview questions of the year or so :

  3. say something spring Which design patterns are used in the design , What design patterns do you use in your actual work

Just came out of the training organization Java How can a programmer find a job without working experience ?

It's a waste of time :

At the beginning, dozens of resumes didn't work , Let's analyze our own problems first , It's impossible that so many copies have not been seen by enterprises , Or the resume is too bad , There's nothing real in it , Too simple , You have to revise your resume , Package yourself or improve your ability

Find your niche

During the interview , The interviewer will ask you about yourself , Learning experience , Work experience , If there is no work experience, it is basically around the foundation and learning situation , If you say nothing , It's just from training institutions , Interviewers interview all kinds of job seekers every day , At this time, his expectation of you will be smaller , There's also some skepticism about your resume , It's better not to talk about projects in training institutions , Datong Xiaoke , These are the projects that come out of the training

Find your own position , Know that you are interested in Java To what extent have you mastered your knowledge , What projects can I do , You'd better not write anything in your resume , Not all the parts of the project are written in , This is no doubt digging a hole for yourself , Find your own position and then go to a company with similar position , It's easier to find a job that suits you .

Must have certain interview skills

Communication is still very important , If it's a group after joining the company , To be able to integrate into . Some projects require teamwork

So brush more questions before the interview , A lot of interview questions , Frequently asked questions and interview questions from big companies , There are also answers , You can leave me a message if you want ( Avoid advertising )

When you come back from the interview, you have to make a reply

Attitude matters

The basic courtesy of going to an interview should be , It's basic to do the written test as well as the written test , The foundation is not solid , Some of the interviews are not needed , Go straight home
