Frequently asked questions in electrician interview

Frequently asked questions in electrician interview

Electrician recruitment mainly focuses on construction and installation, industrial production and other industries, so what are the common topics of electrician interview? The following are the common questions I collected in the electrician interview, I hope to help you!

1, please introduce yourself?

Answer Tip: Most people answer this question too many times and only say their name, age, hobbies and work experience, which are all on their resumes. In fact, what enterprises want to know most is whether job seekers are competent, including: the strongest skills, the deepest knowledge field, the most positive part of personality, the most successful things they have done, the main achievements and so on. These can have nothing to do with learning, or they can be related to learning, but only by highlighting positive personality and ability to do things will enterprises believe it. Enterprises attach great importance to a person's manners. Job seekers should respect the examiner and say "thank you" after answering every question. Enterprises like polite job seekers.

2. What do you think is the greatest strength of your personality?

Answer prompt: calm, clear-cut, firm, tenacious, helpful and caring, adaptable, humorous, optimistic and friendly. After one or two years' training and practical project of Beida Jade Bird, plus internship, I am suitable for this job.

3. Tell me about your greatest weakness?

Answer tip: This question is likely to be asked by enterprises, and they usually don't want to hear what are the shortcomings of direct answers. If the job seeker says that he is narrow-minded, jealous, lazy, bad-tempered and inefficient, the company will definitely not hire you. Never be smart enough to answer "My greatest weakness is to pursue perfection too much". Some people think this answer will make them look better, but in fact they are already in jeopardy. Enterprises like job seekers to talk about their own advantages, add some minor shortcomings in the middle, and finally turn the problem back to advantages and highlight advantages. Enterprises like smart job seekers.

4. What do you think of overtime?

Answer tip: In fact, many companies ask this question, not to prove that you must work overtime, but to test whether you are willing to contribute to the company.

Answer sample: I will work overtime voluntarily if my job requires it. I am single now, I have no family burden, and I can devote myself to my work. But at the same time, I will also improve work efficiency and reduce unnecessary overtime.

5. What is your salary requirement?

Answer tip: If your salary requirement is too low, it is obviously demeaning your ability; If the salary you ask is too high, it will appear that you are overweight and the company cannot afford it. Some employers usually set a budget in advance for the positions they apply for, so their first job is often the highest price they can offer. They only ask you to confirm whether the money is enough to arouse your interest in the job.

Answer sample 1: I don't have a rigid requirement for salary. I believe your company will handle my problem in a friendly and reasonable way. I focus on finding suitable job opportunities, so as long as the conditions are fair, I won't care too much.

Sample 2: I have received systematic training in software programming, and I don't need much training, and I am particularly interested in programming myself. So I hope the company can give me a reasonable salary according to my situation and the level of market standards.

Sample 3: If you have to say the specific figures yourself, please don't say the broad range, then you will only get the smallest figures. It's best to give a specific figure, which shows that you have made a survey on today's talent market and know what kind of value employees with your education have.

6. What is your career plan in five years?

Answer Tip: This is a question that every candidate doesn't want to be asked, but almost everyone will be asked, and more answers are "managers". But in recent years, many companies have established special technical channels. These positions are usually called "consultants", "participating technicians" or "senior software engineers" and so on. Of course, you can also name other positions you are interested in, such as product sales manager, production manager and other positions related to your major. You know, examiners always like enterprising candidates. If you say "I don't know" at this time, you may miss a good opportunity. The most common answer should be "I'm going to make a difference in the technical field" or "I hope to develop according to the company's' management thinking'".

7. What do your friends say about you?

Answer hint: I want to know about your personality and the problems of getting along with others from the side.

Answer sample 1: My friends say that I am a trustworthy person. Because once I promise something to others, I will definitely do it. If I can't do it, I won't say yes easily.

Example 2: I think I am an easy-going person and can get along well with different people. When I get along with others, I can always think from others' point of view.

8. Do you have any questions?

Answer prompt: This question of enterprises seems to be dispensable, but it is actually very critical. Enterprises don't like people who say "no problem" because they attach great importance to employees' personality and innovation ability. Enterprises don't like job seekers asking questions about personal welfare. If someone asks: Is there any new employee training program in your company, can I participate? Or what is the promotion mechanism of your company? Enterprises will be very welcome, because it reflects your enthusiasm for learning, your loyalty to the company, and your self-motivation.

9. What will you do if you are hired by our company through this interview, but after working for a period of time, you find that you are not suitable for this position at all?

Answer hint: I found that the job was not suitable for me for a period of time. There are two situations: ① If you really love this profession, you should keep learning, learn business knowledge and experience from leaders and colleagues with an open mind, understand the spiritual connotation and professional requirements of this profession, and strive to narrow the gap; If you think this career is dispensable, then change careers as soon as possible and find a career that suits you and you love, so that your development prospects will be greater and it will be beneficial to both units and individuals.

10, when you finish a job, you think the way required by the leader is not the best, and you have a better way. What should you do?

Answer prompt: ① In principle, I will respect and obey the work arrangement of the leader, and at the same time, I will also find opportunities to express my thoughts in a private manner to see if the leader can change his mind. If the leader doesn't take my advice, I will finish the work seriously according to the leader's requirements. (3) There is another situation. If the way the leader asks violates the principle, I will resolutely raise objections. If the leader still goes his own way, I will not hesitate to reflect to the superior leader.

1 1. What do you think should you do if you make mistakes in your work and cause economic losses to our company?

Answer prompt: ① My original intention is to work hard for the company. If economic losses are caused, I think the first problem is to find ways to make up or recover the economic losses. If I can't bear the responsibility, I hope the unit can help me solve it. (2) distinguish between responsibility and personal responsibility. If it is my responsibility, I am willing to be punished; If it is someone else's fault in a team I am in charge of, I can't gloat. As a team, I need to help each other finish the work, comfort my colleagues, help them find out the reasons and sum up their experience. Summing up experience and lessons, one can't make mistakes all one's life. It is important to learn from your own or others' mistakes and avoid making similar mistakes in future work. Review your own working methods and analyze whether the depth and intensity of the problem are not enough, leading to avoidable mistakes.

12. What should you do if a job you do is praised by a superior leader, but your supervisor says he did it?

Answer prompt: I won't ask the superior leader to explain this matter at first, but I will take the initiative to communicate with the supervisor, because communication is the best way to solve interpersonal relationships, but there will be two results: ① The supervisor realizes his mistake, and I think I will decide whether to forgive him according to the specific situation. (2) He threatened me even more, so I will not hesitate to ask my superior leader to reflect this matter, because he will have a negative impact on my future work.

13, what do you think about job-hopping?

Answer: ① Normal job-hopping can promote the rational flow of talents and should be supported. Frequent job-hopping is not good for units and individuals and should be opposed.

14. It is difficult for you to get along with your colleagues and superiors at work. What should you do?

Answer prompt: ① I will obey the leader and cooperate with my colleagues. I will look for reasons from myself and carefully analyze whether my poor work makes the leaders dissatisfied and colleagues dislike it. I also need to see if I'm not good at interacting with people. If there is, I will try my best to correct it. If I can't find the reason, I will find an opportunity to communicate with them. If I have any questions, please ask them to point out my shortcomings and correct them in time. As an excellent employee, we should always focus on the overall situation. Even if my leaders and colleagues don't understand me for a while, I will do my job well and learn from them with an open mind. I believe that one day they will see my efforts and smile at me.

15, suppose you work in a certain unit with outstanding achievements and are affirmed by the leaders. But at the same time, you find that your colleagues are increasingly isolating you. What do you think of this problem? what are you going to do？

Answer prompt: ① Outstanding achievements, it is definitely a good thing to get leadership. I will work harder in the future. (2) Review whether your enthusiasm for work is higher than your colleagues' enthusiasm for communication, and strengthen the communication between colleagues and their hobbies. At work, don't hurt others' self-esteem.

16. Have you attended any training courses recently? Tell me about the content of the training course. Is it funded by the company or at its own expense?

Answer prompt: I attended the training course of Beida Jade Bird at my own expense (you can talk more about your own skills).

17, what do you know about our company?

Answer tip: check the company's main business online before going to the company for an interview. For example, your company intends to change its strategy and strengthen OEM cooperation with foreign manufacturers, and the part of its own brand will go through overseas distributors.

18, please tell me your motivation for choosing this job?

Answer hint: I want to know the interviewer's enthusiasm and understanding of this job, and screen those who take the exam on a whim. If they have no experience, I can emphasize that "even if the work is different, I hope to have the opportunity to give play to my previous experience."

19. What is your best technical direction?

Answer tip: There is no harm in showing your enthusiasm for the courses related to the position you are applying for.

20. What's the difference between DC motor and AC motor? Why can both be rotated?

Answer: AC motor is an alternating magnetic field generated by alternating current, which rotates asynchronously. The DC motor moves by the magnetic field generated by the main pole and commutator. The characteristic of DC motor is large torque.

2 1. Tell me what measures (electrical and mechanical measures) need to be taken before using the new motor.

Answer: Before using the new motor, do insulation inspection, check whether there are mechanical cracks in the shell and whether the bearings should be oiled. The new motor depends on what kind of motor, power, speed and even torque, whether it is connected to 220V power supply or 380V power supply, star or triangle. Generally, a new triangular motor with a power of more than 4.5KW is selected to measure the insulation between three phases and the insulation of each relative shell. Mechanically, the rotor rotates flexibly, the bearing has no abnormal noise, the end cover screws are fastened, and the end cover, base and foundation have no cracks.

22. Can you name several cable specifications (as listed in; 0.5mm square,1.0mm square,1.5mm square ——)

Answer: The cables commonly used in factories are all below 180 square meters. Check how many kinds there are.

23. When the inverter is running with motor, use Fluke digital multimeter to measure the frequency of the inverter outlet terminal. Why do you sometimes measure the frequency of several thousand hertz?

Answer: It is impossible for multimeter to measure the voltage and frequency of inverter. Fluke digital multimeter is special. Never used it? Because the inverter frequency modulation mode V/F is different, and the multimeter is calculated according to a certain frequency, so the general multimeter can not reflect the normal reading. The multimeter can definitely measure the voltage, and the frequency of the inverter is directly proportional to the voltage.

24. What is the function of the braking resistor of the frequency converter?

Answer: The braking resistor of the inverter is used to consume the regenerative voltage generated by the motor and will not damage the IGBT module of the inverter. Only when the motor starts frequently or the heavy object falls, the frequency converter can be equipped with a braking resistor.

25. The motor needs to be started frequently. Which frequency converter (inductor or capacitor) should I choose?

Answer: Choose capacitive inverter.

26. A motor runs with a gearbox, and the gearbox is 10: 1. The gearbox is broken. Can you change it to a frequency converter?

Answer: No, because the ratio is the same and the output power is different, there are still many problems.

27. Tell me about the program execution process of PLC.

A: The three processes are scanning external input, intermediate calculation and external output. (According to the list) PLC comes and goes only through control, communication, simulation, servo, stepping and frequency conversion. Recently, nonstandard equipment in servo absolute position control system has been successfully studied for thousands of times.
