What are the tips for interviewing? What do companies value most during interviews?

What are the tips for interviewing? What do companies value most during interviews? The starting point of this question is to test the interviewer's self-perception of the more important factors in the job.

I suggest you answer a few qualities that you value more. Such as: sense of responsibility, efficiency, personal development, etc.

Several qualities that are easier to answer. What do normal school students value most during interviews?

Entering the interview means that your hardware has met the school's requirements. Then during the interview, the school mainly looks at your on-the-spot performance and temperament. You must be very generous during the interview. Good language skills and appropriate behavior will be bonus points. In fact, as long as there are no problems with the lecture or lecture content, the interview is not a teaching design or lecture competition, so you don’t have to worry too much about innovating. Just to be on the safe side. What do Java engineers value most during interviews?

But the first 6 items should be the minimum requirements and are the professional skills that a Java software engineer must possess.

2. Project experience

Project introduction

This system is developed by X and commissioned by Y for Z. The system includes A, B, C, and D. Wait for the module. The system uses Java enterprise-level open source framework E and front-end technology F. The presentation layer uses the G architecture, uses H as the view and I as the controller and implements REST style requests; the business logic layer uses the J pattern, and uses K to implement transactions, logs and security functions, and uses L to implement cache services. ; The persistence layer uses M to encapsulate CRUD operations, and the bottom layer uses N to implement data access. The entire project adopted the P development model. ?Explanation: ?E usually refers to spring (a one-stop choice for Java enterprise-level development); ?F is most likely the jQuery library and its plug-ins or the Bootstrap framework. Of course, if you want to build a single-page application (SPA), it is the best solution It is a front-end MVC framework (such as AngularJS) and a JavaScript template engine (such as HandleBars); G is obviously MVC (model-inspection-control), and the most likely implementation framework is spring MVC. In addition, there are Struts 2, JSF and MyFaces implementation provided by Apache for JSF; ?H is JSP, JSP is used as V in MVC. Template engines (such as Freemarker and Velocity) can also be used to generate views or various files or reports (such as Excel and PDF, etc.); ?I is a Servlet or a custom controller, which is the C in MVC. Of course, Spring MVC provides DispatcherServlet as a front-end controller; ?J is usually a transaction script; ?K should be AOP (aspect-oriented programming) Technology; Memcached and Redis are currently widely used; There are many options, the most likely ones are hibernate and MyBatis. Both technologies can also be used at the same time, but additions, deletions, and modifications are usually handled by hibernate. Complex queries are completed by MyBatis. In addition, TopLink and jOOQ are also excellent persistence layer solutions; The underlying data access has traditionally used relational databases, which can be MySQL, Oracle, SQLServer, DB2, etc., with the advent of large-scale databases, With the advent of the data age, NoSQL (such as MongoDB, MemBase, BigTable, etc.) and other big data access solutions (such as GFS, HDFS, etc.) can also be used; ?P is the development model of the project, which can be a waterfall model, a rapid prototype model, Incremental model, spiral model, fountain model, RAD model, etc.

Project development process

1. Feasibility analysis: Feasibility analysis report, project development plan;

2. Requirements analysis: Requirements Specification OOAD ( Use case diagrams, sequence diagrams, activity diagrams);

Interface prototype: helps understand requirements and derive transaction instruction codes when designing the business layer;

3. Design: outline design instructions, detailed design Instructions;

*Extract business entities (domain objects): class diagrams, E-R diagrams (conceptual design stage);

Layered architecture: determine the technical implementation plan of each layer (specific to The framework used, database server, application server, etc.);

*Business layer design: transaction script mode (transaction: the user sends a request once, which is a transaction;

Script code: a method or a function;

*Transaction script: Encapsulate a request into a method or a function; Transaction script mode: A transaction starts with the opening of the script and ends with Script closure);

*There are three types of objects involved in the business layer: transaction script classes (encapsulating the business process), data access objects (DAO, encapsulating persistence operations), and data transmission Object (DTO, which encapsulates objects in the field of blood loss/anemia), the relationship between the three is the transaction instruction code class combination (aggregation) data access object, both of which rely on the data transfer object forward engineering (UML class diagram generation Java Program code) and reverse engineering (Java code generates UML class diagrams) database physical design (converting ER diagrams into inter-table relationship diagrams, building databases and tables, using tools to insert test data);

3 , Coding;

4. Testing: test reports, defect reports;

*Unit testing: Check and verify the smallest testable unit in the software, in Java it is the class The method in the test can be implemented using the JUnit tool;

*Integration testing: Integration testing is also called assembly testing or joint testing. On the basis of unit testing, all modules are assembled into subsystems for testing according to design requirements;

*System testing: Combine the confirmed software, hardware, peripherals, network and other elements into Together, we conduct various assembly tests and confirmation tests of the information system. System testing is a test for the entire product system. The purpose is to verify whether the system meets the definition of the requirement specifications and to find out the inconsistencies or contradictions with the requirement specifications. Thus, a more complete solution can be proposed;

*Acceptance testing: After the software product has completed unit testing, integration testing and system testing, the software testing activities are conducted before the product is released. It is the last stage of technical testing, also known as delivery testing.

The purpose of acceptance testing is to ensure that the software is ready and can be used by end users to perform the specified functions and tasks of the software;

5. Delivery and maintenance: user manual, operation manual;

6. Interview questions

Which company was the project developed for? What is the investment in the project?

How many people were involved in project development? What is the ratio of testers, developers, and project managers in the entire team?

How long did the project take to develop? What is the total code amount of the project? How much code do you have?

What development model or development process was used for the project? What is the structure of the project? What is the technology selection for the project?

What responsibilities did you play in the project? Do you have frequent meetings or work overtime? What are the gains or lessons learned after completing the project?

What was the most difficult part of the project? How to resolve various conflicts encountered during team development?

7. You can ask the interviewer questions during the interview

I noticed that you used X technology. How did you solve problem Y?

Why does your product use X technology instead of Y technology? As far as I know, although X technology has benefits A, B, C, etc., it also has problems D and E, and technology Y can solve problems D and E.

I am not too familiar with the X technology you are talking about, but I feel it is a good solution. Can you tell me more about how it works?

How does your team plan the project? How many regular meetings are there a week? What is the approximate amount of coding per week?

The only solution I can think of for problem X is Y. How would you solve this problem?

8. S.A.R. Rule The S.A.R rule means to first describe the problem scenario, then explain the actions you took, and finally state the results.

9. Interview principles

Have a moderate voice, speak clearly, smile, have a positive personal image, and be polite.

Take the initiative to talk to the interviewer about topics that interest him and satisfy the interviewer.

Take the initiative and boldly talk to the interviewer about content that you are familiar with and experienced: projects, technical points, etc., so as to maximize your strengths and avoid weaknesses.

Be sure to express that you really want to get this position and that you are willing to learn technologies you don’t understand.

Put forward reasonable treatment requirements based on your actual level.

10. Self-evaluation

Learning ability (people in the IT industry need to constantly understand new technologies, tools and methods)

Team awareness (compared to Personal heroism, the IT industry advocates teamwork)

Stress resistance (the work intensity of many IT companies is relatively high) During an interview, what does a good company pay most attention to?

Hello!

In daily life, we will also encounter such a situation: on certain occasions, we suddenly feel that our clothes are awkward and incompatible with the people or the environment around us, so we act with embarrassment. I just look forward to leaving early.

During the interview, you will inevitably feel nervous, and you should take precautions against similar psychological barriers. Although the interview mainly examines the inherent qualities of the candidates, practice has proved that the image of the candidates often brings different effects. Furthermore, in interpersonal interactions, being dignified and neatly dressed reflects respect for others and society, and shows a person's mental state and degree of civilization. Of course, it has also become one of the standards for measuring character during interviews. So don’t stop until you look your best.

1. Hair and beard An interview is a very formal occasion, so don’t make your hair look weird. Just keep your hair neat, clean, natural, and showing off your entire face. For male students, they should not be shiny and wear a lot of mousse, like a cream boy, which has no masculinity; they should not have their hair permed or dyed in other colors; and their hair should not be too long. For female students, the shawl hair should not be left unchecked. It should be slightly curled. The hairstyle can also be specially styled, but it should be popular. Avoid too many headdresses and excessive attire. On occasions like interviews, be generous and natural. As a rule, don’t have any “fashionable hairstyles.” The hairstyle should be consistent with your status as a student. Maybe you will say that it is okay to do these, but that is not enough. When you arrive at your interview, your hair may be a little disheveled. So, don’t forget to carry a small comb and a small mirror in your pocket. Whether you are a man or a woman, if you think you should go to the barber shop before the interview, it is best not to go straight from the barber shop to the examination room with unbrushed short hair on your collar and the fragrance of styling water on your head, as if you It's like I only get a haircut every interview. Men should have a thorough shave before the interview. Be careful not to damage the panel when trimming. Scars on the chin or neck not only affect the appearance of the face, but also stain the collar of the shirt. If you have a big beard, you must shave it clean. An unkempt beard will make the examiner think you are rude, and a thick beard may inadvertently mean "I need a little loneliness, please stay away from me." If you were an examiner, I believe you wouldn’t want to feel this way. Therefore, you need to pay more attention to your appearance and show your most handsome, that is, the youngest face in front of the public.

Regardless of boys or girls, the use of perfume should also be kept simple to make people feel natural. Regarding various accessories, it is best for girls not to wear earrings, earrings, necklaces, rings, bracelets and other accessories. Even if they do wear them, they can only wear one or two of them. Some boys like to hang a jade pendant on their chest, while others like to wear a ring. It is better to take them both off. After you have deliberately modified it and come to the employer, you might as well check it one last time a few minutes before the interview to make sure there are no mistakes. Whether it is clothing or appearance, you should follow one principle, that is, you should not dress yourself up as a completely social image of "hardened in the battlefield and sophisticated", but should maintain the temperament and innocence of a college student. It is very important to let the examiner feel your student atmosphere. There was once a female college student who, in order to show off her beautiful image before an interview, spent all her money on a high-end black skirt and had a beauty treatment in a beauty salon. She looked more noble and beautiful. Her image is indeed very elegant, but at the interview site, her well-intentioned dressing up will actually bring disadvantages to herself. When the examiner admired her beauty, he began to have bad judgments about her: "Such high-end clothes, but does this look like a student?" "She likes to dress up too much, can she work safely?" "It seems like she Her financial situation is good, is she a pampered young lady? Can she adapt to the hard work of a national civil servant?" The more experienced examiner saw through the connotation behind her deliberate dressing up and said, "This "You're not just pretending," "You're not mature enough or stable enough!" So when dressing up, you must have a clear positioning of your student identity, and you must realize that you are participating in a job interview, not with others. Boyfriend date.

Finally, hands are one of the most mobile parts of the human body and are often the focus of people’s attention. This doesn't mean you should put makeup on your hands before the interview, but it is necessary to have your hands clean and your nails neatly manicured. Nails are generally as long as the fingertips and should be brushed clean of oil and dirt. Professional ladies are generally not advised to keep their nails long as it may affect the normal operation of office equipment. What does the company care about most during the interview?

First of all, you have to capture the heart of the company! Very important, this is related to your emotional intelligence. What the company values ??most is not what they say, but what they say. What you can bring to the company, that is, whether it can make money for the company! Bring profits, this is the most important! So when you go to market, you need to know what to say and focus on this aspect!

Also, regarding wages, you Just say it is 580 (minimum living allowance). It depends on what results you can achieve for your boss in the future.

I wish you good luck!

Let me know the results. , Haha GOOD LUCK!

What companies care about most is whether you meet the requirements of their position and whether you have similar experience. In short, companies hope that the value created by employees exceeds their remuneration. When interviewing UI designers, what do companies value most?

? A. Have user experience awareness

When you are interviewing, you yourself are the product, and the interviewer is Users, as UI designers, have to consider how to present their products to users as quickly and best as possible. Be aware that users are around you, and always pay attention to what users think of your designs and products. Although the work can also be viewed on PC, the user experience will be better if it is shown directly to the examiner on a mobile phone.

As a UI designer, putting your work on your mobile phone is a manifestation of professionalism. Whether it is an online product or a single image, regardless of whether the design is good or bad, the key is whether it is present or not. Without this awareness, some companies will simply cut them off.

B. Make adequate preparations

Have you done your homework in advance? Have you reviewed company information? Have you downloaded the company APP? The recruiter hopes that you can take the initiative to learn about the company in advance.

This group of people will be classified as a higher priority by the company. Some people not only looked at the product, but also analyzed the product concept and market positioning, and recognized the company culture.

Even if such candidates have poor design skills, the company is willing to spend time cultivating them.

C. Have the courage to admit mistakes

Some recruiters will deliberately ask pointed questions, such as pointing out flaws in your work and design mistakes. Their real intention is to test whether you can Admit mistakes and take responsibility. Faced with the shortcomings, some interviewees tried every means to defend themselves, and even made excuses to blame their bosses and product managers. The recruiter believes that such a person has no sense of responsibility and the work progress will be very slow.

For a company, it doesn’t matter if you make mistakes, what matters is the attitude towards mistakes.

D. Have a desire to learn

And the desire to learn is the driving force for designers to progress. UI designers need to pay attention to more knowledge than graphic designers, involving life, philosophy, and life principles to obtain inspiration.

For example, some companies will ask you "What books have you been reading recently?" The books here are not limited to professional books. Liking to read books is conducive to the designer's imagination and cultivates the designer's observation, understanding and thinking ability of life. The understanding of society and human nature promotes the designer to improve the user experience. This kind of designer has his own spark. Just add a handful of firewood and it will burn brightly.

E. Have a sense of sharing

Companies tend to choose designers with a sense of sharing. Generally speaking, designers who are willing to share ideas are beneficial to both personal growth and team building.

For example: The interviewer asks you "How do you eat at noon?", which is to test your awareness of sharing. People who are willing to eat with everyone, order meals for everyone, and enjoy delicious food are the type that companies prefer.

F. Design ability

Examining design ability is basic, but we put it in the last item. In the eyes of some companies, design ability can even be regarded as the least important compared with other qualities. What do most companies value most in an interviewer?

Whether it matches the professional requirements. For example, it is difficult for introverts to do sales, and it is difficult for lively people to do a single repetitive job.

Everyone has their own characteristics, and companies want people who are qualified for their positions.

Whether you can stay in a company for a long time? After all, it takes time to cultivate and become familiar with the company's business
