Basic Electrical Interview Questions
The following are some of the types of questions electrical engineers come across on job interviews. Besides, there are various categories of problems regarding a job interview for electrical engineering graduates.
Given below are the interview questions for BE/B.Tech Electrical Engineering and ME/M.Tech Electrical Engineering graduates.
- General Questions in Electrical Engineering Interview
- Behavioral Questions in Electrical Engineering Interview
- Electrical Engineering Technical Questions
General Questions
These are the types of questions that are asked to start the conversation. These typically come at the beginning of the interview and act as an icebreaker before getting into the harder questions.
Below are some of the general interview questions.
- What is your background?
- Can you explain to me the reason to become an Electrical Engineer?
- What are your strengths and weaknesses?
- Explain what are your short-term and long-term goals?
- What motivates you to succeed?
- What do you think separates you from other candidates?
- Which Electrical engineering computer software are you comfortable dealing with?
- What is your specialty within electrical engineering?
- What qualities do you have that would be helpful in this job?
- Where did you get your electrical engineering degree, and in which class did you excel?
Behavioral Questions
These are the questions generally asked to know how one behaves in the workplace and how one makes a professional decision.
Below are some of the behavioral interview questions.
- Tell about a challenge you faced and how you solved it.
- Describe the most successful teamwork experience. What made it so successful?
- How did you manage a strict deadline?
- What was the toughest decision that you’ve had to make within the last year?
- Explain a few projects that you have helped design. How did your involvement improvise the outcome?
- Tell about the time when you went above and beyond to get the job done. How did you challenge yourself along the way?
Technical Questions
Technical questions will assess your knowledge of electrical engineering concepts and theories. In addition, if anybody has a specialty, they may test the understanding of your specialized area of electrical engineering as well.
Some of the technical interview questions are as follows:
- Differentiate direct and alternating current.
- Explain the Nortons Theorem in a single sentence.
- What are some of the most causes of transformer humming?
- What are single pole and double pole circuit breakers?
- What is the difference between alternator & generator?
- Explain your understanding of AES, the Australian Engineering Standard 61508?
- What is analog to digital conversion of signals?
- How can a reverse polarity be fixed & what do you mean by it?
- Explain What is Zener diode?
- Explain the different methods of producing electricity? Give examples
- What are the effects of electricity?
- How will you judge the supply is in AC or DC on-premises?
- What is dielectric strength?
- Mention the factors on which the dielectric strength depends.
- Suppose a client is using chlorine gas as a sanitizer. However, the facility is only 300m from a public area and poses a significant risk. What decision-making process would you take the client through to remove the threat?
Please Note: The list of questions only gives a glimpse of the surface of the information that you may be asked to provide during your interview. In addition, one should be prepared for different situational questions that deal with workplace problems under specific circumstances.
