This year's cold winter has lengthened the job hunting time of many professionals. In addition to the fiery gold, silver and gold in the past, June has also become a hot period for recruitment. Under this special situation this year, the pressure of competition has increased. The demands of consumers have also increased.
Many small partners are faced with such a situation. They worked hard to get an interview opportunity, but they overturned due to various reasons:
"I can't show my true strength during the interview." "
I can't grasp the key points when answering the interviewer's questions."
"Nervous, stuttering, and don't know how to best present myself."
Especially in the current Android interview, most companies put more and more emphasis on the understanding of the Framework layer and the ability to control the UI framework, in addition to the requirements for basic skills such as language and coding of job applicants. Complete project experience and multi-terminal knowledge have also become important bonus items.
First look at the project experience
When the interviewer asks this question, there are actually two meanings. One is to understand your project capabilities through your explanation, and the other is to actually understand your project in more detail through your narration. It is not consistent with the project experience written on the resume, and it is also used to determine whether your project experience is real.
Normally, we put the project with the highest gold content in the first column on our resume. When asked this question, we should focus on this one, and describe the business function of the project clearly. Specifically, we can pass the following Point to elaborate:
1) Briefly introduce the project
2) List the functions implemented by the project
3) Tell the technology and architecture of the project, focusing on which new technologies or good architectures are used, and emphasize the project The difference from other projects
4) You can express the scale of the project implicitly in words to highlight our capabilities
5) Tell us in detail which section you are responsible for in the project
Through the above five points, the three-dimensionality and authenticity of the whole project can be well reflected. It can not only express your personal ability in detail, but also make the interviewer feel that you really have project experience. , in line with company standards.
Not to mention the basic skills such as basic language and coding after that, this is a must for an excellent programmer.
The second is the underlying source code understanding
For us android programmers, this is more about Framework knowledge content.
Framework, as the Android framework layer, provides many APIs for App to call. Many mechanisms are packaged by Framework for App to use. If you don’t know the principles of these mechanisms, it is difficult to optimize a specific app or system according to the market. , such as most of the vehicle-mounted systems on the market or the systems of major mobile phone manufacturers.
It may be unfamiliar to many android programmers at work, but people who change jobs now know that it has become a must-ask question in interviews. If you don’t know it, you can only find a job.
So the editor sorted out my notes in the process of learning the Framework, and sorted out some of the questions that are often involved in the Framework interview process. For the knowledge points that have not been summarized, you are welcome to raise them in the comments.
