foreword
In the blink of an eye, has it been so long since reading? , It has been almost 4 years since I graduated from a bachelor’s degree in May 2018 and joined a small company. Some time ago, the social recruiter wanted to find a new job, and spent more than a month reviewing and interviewing. A few days ago I got an offer from Huawei, and I would like to share my experience with you here. I wish all students who want to find a job can go to their favorite company!

Huawei Two Sides
Bug level
Crash (Blocker) Level 1 bug, must be modified first
(1) System crashes, crashes, and endless loops caused by routine operations
(2) Security issues that cause data leakage, such as leakage of account private information caused by malicious attacks.
(3) Involving money, such as payment software, miscalculation of money
Critical (Critical) level 2 bug
(1) Important functions are not implemented (such as: WeChat has no voice chat, circle of friends, etc.)
(2) The error spread widely, affecting the normal realization of other important functions
(3) Program crashes, crashes, and endless loops caused by unconventional operations (unconventional operations: operations that users will not perform when using the software)
(4) Defects that are unacceptable in appearance (for example: distortion, compression, and complete deformation of the cover image of the live broadcast platform)
(5) Password display in plain text
General (Major) level 3 bug
Defects that do not affect the operation of the product, do not become the cause of failure, but have a great impact on the appearance of the product and the next process
(1) Secondary functions cannot be realized normally
(2) The operation interface is wrong (including the definition of the column name in the data window, the meaning is different) eg: the column name is different from the content under the column name
(3) Query error, data display error
(4) Simple input restrictions are not controlled by the front end; (format display, such as the format judgment in login and registration can be judged by the front end)
(5) The delete operation does not give a prompt
Minor Level 4 bugs
The program is not beautiful on some displays, does not conform to user habits, or some text errors
(1) The interface is not standardized
(2) The description of the auxiliary instructions is not clear
(3) The prompt window text does not use industry terminology
(4) There are text errors in the interface
(5) Improvement suggestions: Suggestions for improving product quality, including new requirements and improvements to requirements
Huawei on three sides
What are the modes of processes and threads?
3 modes:
1. Inherit thread
2. Implement the runnable interface and implement the Callable interface to create a Thread thread through the FutureTask wrapper
3. Use ExecutorService, Callable, and Future to implement threads that return results.
-----Inherit the Thread class to create threads----
1d Define a subclass of the Thread class, and rewrite the run() method of this class. The method body of this method is the task that the thread needs to complete. The run() method is also called the thread execution body.
2 Create an instance of the Thread subclass, that is, create a thread object
3 Start the thread, that is, call the start() method of the thread
----- Implement the Runnable interface to create threads -----
1 Define the implementation class of the Runnable interface, and also rewrite the run() method. This run() method is the same as the run() method in Thread, which is the execution body of the thread
2 Create an instance of the Runnable implementation class, and use this instance as the target of Thread to create a Thread object. This Thread object is the real thread object
3 The third part is still to start the thread by calling the start() method of the thread object
----- Using Callable and Future to create threads -----
1. Create an implementation class of the Callable interface, implement the call() method, and then create an instance of the implementation class (starting from java8, you can directly use Lambda expressions to create Callable objects).
2 Use the FutureTask class to wrap the Callable object, which encapsulates the return value of the call() method of the Callable object
3 Use the FutureTask object as the target of the Thread object to create and start the thread (because FutureTask implements the Runnable interface)
4 Call the get() method of the FutureTask object to obtain the return value after the sub-thread execution ends
HR face
1. Talk about a project that impresses you the most
2. What are the responsibilities in the project and what has been accomplished?
3. What difficulties did you encounter and how did you solve them?
4. Have you ever served as a leader? What is the most important ability?
5. Tell me about your strengths
6. Do you feel that your ability to resist stress is strong?
7. What do you think about overtime work?
8. What do you want to ask?
After returning from the Huawei interview, in order to let everyone have better interview materials, I spent more than a month to make a summary of the software test interview questions on the market, and sorted out a pdf, which is enough for everyone to read The question is reviewed! Unless the interview questions are tricky, it won't bother you.
