General knowledge interview of electrical automation

1. What are the main processes that should be paid attention to in the interview of electrical automation?

As an automation engineer who worked for five years, I experienced a job-hopping experience.

After working in a design institute joint-stock company under the SASAC for three years, I feel that I have made small achievements, and the requirements for salary and treatment are constantly expanding, especially working with Siemens ABB. Looking at their attractive working environment, I feel that I must work in such a company, for nothing but fame! Hehe, it seems that the idea at that time was so naive. At first, I decided to jump ship and want to go to Siemens, not only because I like it, but also because Siemens has a close cooperative relationship with our company in the industrial automation control industry, so it is easier to jump ship.

However, with more interviews, this idea was gradually dispelled. Siemens is not as attractive as I thought.

Siemens industrial control in Beijing is mainly divided into I &；; S and a &；; D Two groups (currently, there are two former colleagues who work with friends at I&S). When I interviewed two years ago, I went to almost all the departments I could go to. I&; S mining, steel rolling department, A &；; D automation department and industrial network department. I also know Siemens very well.

Now it seems that I still like Siemens. After all, it is a leader in the industry. Although many aspects are a bit messy, I will try it if there is a good title.

Continue Schneider in the industry, Schneider is a company with relatively high salary and good reputation. I remember that two departments informed me of the interview at that time, and I don't know why the other one was cancelled.

As far as I know, it is to avoid internal competition. But the final result proved that I chose the wrong one.

The interview was in Yizhuang, and after entering it, it was not as elegant as expected. I just saw many young people staring at the computer with headphones and constantly answering questions. No, it's the hotline. It's the last job I want.

Listening to the manager's endless talk, I just answered. In the second interview, the manager said it was almost enough. I just met the big boss. I refused his request and gave up. I chose to give up.

I never thought I'd call. After all, he is also a leader in the industry, an American company. Although the environment is not as good as Siemens, it is ok.

But the only thing that bothers me is the position, an application engineer who controls valves. Also, HR was late.

The interview experience was also very unpleasant. I filled out the form, took the written English test, and finally met the manager, and then it was gone. I work in Alstom now. It was my present boss who spoke kindly during the interview of engineer C.

I successfully passed two departmental interviews, and then the last round was to meet the boss of ECS Asia Pacific. An Italian, speaking English I don't understand, doesn't know how he came. He thought he would lose this opportunity, but he did give me a proposal. To sum up, I think job hopping is an impatient process. I always thought the opportunity was very good when I interviewed (of course, I don't think Siemens is good because I don't want to travel all the year round), but now I think my present job is the best.

Two years have passed, during which I went to Japan for two months, Sweden, France and Denmark. In a word, I have benefited a lot (although I haven't improved much technically), seen a lot of the world and strengthened my confidence.

As for ABB, I have been there twice, during my stay in Alstom. I guess I want too much leisure and my qualifications are still young. Netizen exchange: Xiao Bing _9 15: It is rare to see such a real post in the workplace.

I was going to sit down and watch your big discussion and learn some knowledge by myself. Unfortunately, there are few people, because I graduated automatically.

Actually, I just graduated. I didn't go to the company until July.

The company mentioned by the landlord is the yearning of our automation people. For the automation major, it is really too complicated to learn in school.

C language, single chip microcomputer, PLC, digital electricity, analog electricity, motor drive, power electronics, process control, motion control and the most basic automatic control. In fact, I think there is great development behind each door, and it is really difficult to choose.

Most of them are at a loss about the future career development direction. I wonder if the landlord can guide the younger generation with his own experience.

3L Hello, soldier. You only worked for a year. In my opinion, it takes at least three years to accumulate. Don't be too impetuous. The accumulation of knowledge and experience is the most important thing. Besides, don't forget to learn English. Good skills and good English have an advantage in this industry. This is my experience! Rainlyy: I wonder what the development prospect of automated girls is? LZ, can you help me? The automated little girl thanked me first. Geming323: automated girl? Of course, the girls did a good job. It depends on the individual. I think either I said it or I did it.

Anyway, you just have to work hard. You just need one direction. It is true, but not absolute, that girls' automation is restricted in some places and even treated unfairly in job hunting.

If you are interested in this, you can try to continue doing it, and there are places that suit you. Rowenchang, it's very kind of you to do a lot of tests in the automatic interview. Is it important to pass the interview? After this threshold, everything will be ok. When you meet something you can't do, just say no or pretend to ask questions. A little silly. I'm sorry, geming323 will, but it won't.

There is nothing to hide. If you have no ability, you will be eliminated if you go in. Many people who went in with me, even before me, have been fired.

2. What professional knowledge did you ask in the interview for electrical specialty?

Generally speaking, enterprises don't require much of your professional knowledge.

Because what I learned in college may not be used at all.

Even if it is used, it is a small part.

For example, before going to ABB, I asked you to design transformers or high and low voltage cabinets, basically learning the principle.

The real design university has never taught enterprises at all, and we know that our university has not learned it.

Chinese medicine will naturally give you relevant training after entering the enterprise, so enterprises often pay great attention to your self-motivation and learning ability when recruiting.

The most important thing in design work is to be able to sit still and learn professional knowledge patiently.

Therefore, professional knowledge need not be particularly emphasized.

Electrical engineering is a very broad major, and it is difficult to determine what you will do in the future.

And I don't know which direction you study and which unit you want to go to.

These are not very clear, so it's hard to say.

3. Interview with Electrical Automation

Automation is too extensive,

It's best to know the type of your interview unit and review it accordingly.

For example, machinery, review electrical control, PLC, frequency converter and so on.

If it is chemical, electrical and instrument control, PLC, frequency converter, WINCC, DCS,

Like electrical control, you need to draw a Y-triangle for step-down starting, and two double switches control Yi Deng.

PLC and WINCC programming communication, this meeting

How to set the inverter to start and stop?

DCS does simple control, such as boiler feed water control.

When answering the examiner, if I ask you a question that I can't, such as asking you to draw a Y-triangle to start the buck, you won't. You can say that you will draw a positive and negative.

Ask you about frequency conversion drive, you won't. You can explain how to set the start and stop of the frequency converter.

Sometimes you can be flexible and let the examiner know that you know his problem in other ways, so that the examiner feels that you are plastic.

Finally, good luck.

4. Interviews for electrical engineering and automation majors generally ask the basic knowledge of those majors.

The major of electrical engineering and automation is the key major of national defense.

This major has four major directions: electrical machinery and appliances, power system and its automation, industrial automation and building automation. Cultivate compound senior engineering and technical personnel with wide knowledge and strong adaptability who are engaged in R&D, engineering design and management in the fields of electrical machinery, electrical appliances, power system, industrial automation and building intelligence.

This major has the characteristics of combining strong and weak electricity, combining electrical technology with electronic technology, combining components with systems, and combining computer technology with control technology and communication technology. The main courses include circuit, electronic technology foundation, electrical engineering, computer composition technology, automatic control theory, power electronics technology, detection and signal processing, computer simulation technology, industrial control network, embedded system principle and application.

In addition to studying for master's degree, graduates mainly work in national scientific research institutes, large and medium-sized enterprises, state organs, institutions of higher learning, electrical and information high-tech industrial companies and other units. The major of electrical engineering and automation aims to cultivate compound senior engineering and technical talents with distinctive characteristics who can work in the related fields of electrical engineering and automation, with special emphasis on the cultivation of students' ability to acquire knowledge and all-round quality.

Graduates of this major have strong adaptability, wide employment scope and high employment rate, and the employment rate has reached 100% in recent three years. Graduates are mainly employed in power system research, design, production, testing, construction, management, education and other units, engaged in the design, operation, installation, debugging, scientific research and teaching, technology development, technology management and other units of electrical engineering in power systems, power plants and related industries.

Introduction of electrical engineering and automation: The tentacles of electrical engineering and automation extend to all walks of life, from the design of a switch to the research of aerospace aircraft. This major can be engaged in the fields of system operation, automatic control, power electronics technology, information processing, experimental technology, research and development of electronic and computer technology, economic management and application, etc. It is a "compound" senior engineering and technical talent with wide caliber.

There is a great demand for high-level talents in this field. It is estimated that with the entry of large foreign enterprises, there will be a big gap in this professional field, and there is likely to be a shortage of talents.

I. Professional Comprehensive Introduction Electrical Engineering and Automation is a new discipline in the field of electrical information, but it has developed very rapidly and is now relatively mature because it is closely related to people's daily life and industrial production. It has become an important part of high-tech industry, widely used in industry, agriculture, national defense and other fields, and plays an increasingly important role in the national economy.

Control theory and power network theory are the basis of electrical engineering and automation specialty, power electronics technology and computer technology are its main technical means, and also include research fields such as system analysis, system design, system development, system management and decision-making. There are also some characteristics of this major, that is, the combination of strong and weak electricity, electrical and electronic technology, software and hardware, the interdisciplinary nature, and the integration of power, electronics, control and computer, which makes graduates have strong adaptability and is a "wide-caliber" major.

The major of electrical engineering and automation has a strong attraction to the majority of candidates, and it is a hot major. The entrance score of college entrance examination is often much higher than other majors. The main reasons for this situation are: ① easy employment, good working environment and high income; ② The name is nice, and the professional content is attractive to students; Social propaganda and public opinion orientation are beneficial to it. The development prospect of this major is very good, the research results can be easily transformed into real products, and the benefits are also considerable.

His creative research ideas have attracted many candidates, which is indeed a good place to display his talents. However, in view of the current situation in China, candidates should pay attention to the following two points when applying for this major: (1) Give full consideration to their own interests.

Maybe I wasn't interested in this direction, but many people said there was, so I was "interested". This is very unfavorable for future development. After all, interest is the best teacher.

(2) Measure your comprehensive quality. The major of electrical engineering and automation needs to have a solid foundation of mathematics and physics and a strong comprehensive ability of foreign languages, so as to prepare for mastering and flexibly using professional knowledge in the future.

Although this major has a great demand for talents, there are many people to choose from. Without a very strong comprehensive quality, it is difficult to stand out and achieve excellent results. Perhaps this is unacceptable to many aspiring candidates.

Of course, the two possibilities mentioned here are also related to students' personal pursuit. If one's pursuit is limited to a better job, this major is really a good choice. But if you want to make a breakthrough contribution in scientific and technological innovation, you must build on your personal strength and efforts. Pie never falls from the sky for no reason.

Because this major has a wide range of research, good application prospects and relatively high professional quality of graduates, the employment situation is very good. Our country is in great need of professionals in this field now, and it is inseparable from the work of these professionals from small families to the whole society.

Usually, after graduation, students can choose state-owned quality and technical supervision departments, scientific research institutes, industrial and mining enterprises, etc. It can also be some foreign-funded and private enterprises, and the treatment is of course considerable. If students are strong enough and have accumulated good research results during their studies, they can start their own businesses and create their own sky.

It should be pointed out that, because the research essentials of this major are ahead of us abroad, it is a good choice to go abroad for further study if you want to have further development and establish your leading position in this direction in China. Second, the development of professional education Electrical engineering and automation is a new interdisciplinary specialty which integrates science, engineering and literature, and integrates mechanical engineering, art and computer design.

The main subjects are electronic engineering, computer science and technology, control science and engineering. This major came into being in the 1970s. First of all, in Oxford University, the DC control mode was realized for the first time. At that time, the driving voltage of the actuator was DC and the control voltage was DC.
