JOB INTERVIEW PREPARATION QUESTIONS


Most Common Interview Questions (with possible answers)

The exact questions you will be asked in any interview will vary according to the type of interview, type of position, and career field you are pursuing. However, there are some questions that occur frequently across a wide spectrum of interview types, so be prepared with strong answers!

1. Can you tell me a little about yourself?
The employer is looking for general information about your academic history and interests that ultimately led you to choose your major and career path.
Avoid answering this question with personal details (e.g., where you grew up, likes/dislikes, etc.).

2. What do you know about our company and why do you want to work for us?
Make sure you have done your homework! Has the company been in the news lately? Who are the key people in the company you should know about?
Emphasize the strengths and experience that you would bring to the company rather than talk about what the company would do for you.

3. Why should I hire you?
Present at least three examples of your strongest personal qualities or skills that would be relevant to the position, e.g., "I have excellent organizational skills; I developed the business model for our student project, assigned 12 group members to tasks, and followed up on training with each person."

4. How would you describe your ideal working environment?
The interviewer wants to know what type of workplace is most comfortable for you (e.g., noisy, quiet, formal, casual, etc.) in order to figure out whether or not you'd be a good fit for the company. Be honest! It's as important to be happy with your workplace as it is to be happy with the work itself.

5. Can you tell me about your three greatest strengths/Do you have any weaknesses?
Be positive and focus on examples of at least three strengths that would be valued in almost any workplace (e.g., you work well under pressure, you motivate others, you have outstanding attention to detail).
Additional personal qualities that most employers look for include honesty, collegiality, reliability, integrity, common sense, and enthusiasm.
Be careful with the weaknesses you choose to discuss—for example, don't say that you're "not a morning person" or that you are always late. Focus on one work-related weakness and talk about how you are working to improve.

6. How would someone who knows you well describe you?
Think of how a former boss or colleague—rather than a friend, family member, or significant other—would describe you.
Focus on attributes that would be useful in the workplace, e.g., "When I was a work-study student, my supervisor always appreciated my creativity on projects and the attention to detail I showed in my work."

7. What do you like to do in your spare time?
Emphasize any volunteer work you like to do (if applicable) or your involvement with student organizations related to your major/field of study.
If you don't participate in extracurricular activities, emphasize positive personal interests that contribute to your own health or well-being (e.g., reading, working out, playing sports, playing a musical instrument).

8. How did you choose your college/university/company?
Your response should focus on good academic reputation and strong engineering (or other major) program. It's also okay to mention legacy reasons, e.g., if your parents chose the same or similar college /university/ company, and it is a family tradition.

9. Can you describe a challenging situation that you have faced during your college years, and how you resolved it?
This a behavioral question designed to see how you approach and solve problems. Choose a fairly benign situation (such as a conflict with a roommate) and focus on how you worked collaboratively to find a solution.

10. What are your salary requirements?
Although the topic of salary doesn't usually come up in an initial interview, some recruiters will want to know whether or not you are aware of the average pay rates for students or recent graduates in your major. Try not to give a specific salary figure; if you are pressed to do so, give a range. You might find this information about average starting salaries to be helpful in coming up with an acceptable range.

Electrical Engineering Interview Questions and Answers

1. Why star delta starter is preferred with induction motor?

Star delta starter is preferred with induction motor due to following reasons:
• Starting current is reduced 3-4 times of the direct current due to which voltage drops and hence it causes fewer losses.
• Star delta starter circuit comes in circuit first during starting of the motor, which reduces voltage 3 times, that is why current also reduces up to 3 times and hence less motor burning is caused.
• In addition, starting torque is increased and it prevents the damage of motor winding.

2. State the difference between generator and alternator

Generator and alternator are two devices, which converts mechanical energy into electrical energy. Both have the same principle of electromagnetic induction, the only difference is that their construction. Generator persists stationary magnetic field and rotating conductor which rolls on the armature with slip rings and brushes riding against each other, hence it converts the induced emf into dc current for external load whereas an alternator has a stationary armature and rotating magnetic field for high voltages but for low voltage output rotating armature and stationary magnetic field is used.

3. Why AC systems are preferred over DC systems?

Due to following reasons, AC systems are preferred over DC systems:
a. It is easy to maintain and change the voltage of AC electricity for transmission and distribution.
b. Plant cost for AC transmission (circuit breakers, transformers etc) is much lower than the equivalent DC transmission
c. From power stations, AC is produced so it is better to use AC then DC instead of converting it.
d. When a large fault occurs in a network, it is easier to interrupt in an AC system, as the sine wave current will naturally tend to zero at some point making the current easier to interrupt.

4. How can you relate power engineering with electrical engineering?

Power engineering is a subdivision of electrical engineering. It deals with the generation, transmission, and distribution of energy in electrical form. Design of all power equipment also comes under power engineering. Power engineers may work on the design and maintenance of the power grid i.e. called on grid systems and they might work on off-grid systems that are not connected to the system.

5. What is the various kind of cables used for transmission?

Cables, which are used for transmitting power, can be categorized in three forms:
• Low-tension cables, which can transmit voltage up to 1000 volts.
• High-tension cables can transmit voltage up to 23000 volts.
• Super tension cables can transmit voltage 66 kV to 132 kV.

6. Why back emf used for a dc motor? highlight its significance.

The induced emf developed when the rotating conductors of the armature between the poles of a magnet, in a DC motor, cut the magnetic flux, opposes the current flowing through the conductor, when the armature rotates, is called back emf. Its value depends upon the speed of rotation of the armature conductors. In starting, the value of back emf is zero.

7. What is the slip in an induction motor?

Slip can be defined as the difference between the flux speed (Ns) and the rotor speed (N). The speed of the rotor of an induction motor is always less than its synchronous speed. It is usually expressed as a percentage of synchronous speed (Ns) and represented by the symbol ‘S’.

8. Explain the application of storage batteries.

Storage batteries are used for various purposes, some of the applications are mentioned below:

• For the operation of protective devices and for emergency lighting at generating stations and substations.
• For starting, ignition, and lighting of automobiles, aircraft, etc.
• For lighting on steam and diesel railways trains.
• As a supply power source in the telephone exchange, laboratories, and broadcasting stations.
• For emergency lighting at hospitals, banks, rural areas where electricity supplies are not possible.

9. Explain advantages of storage batteries

Few advantages of storage batteries are mentioned below:
• A most efficient form of storing energy portable.
• Stored energy is available immediately because there is no lag of time for delivering the stored energy.
• A reliable source for supply of energy.
• The energy can be drawn at a fairly constant rate.

10. What are the different methods for the starting of a synchronous motor?

Starting methods: Synchronous motor can be started by the following two methods:
• By means of an auxiliary motor: The rotor of a synchronous motor is rotated by an auxiliary motor. The rotor poles are excited due to which the rotor field is locked with the stator-revolving field and continuous rotation is obtained.
• By providing damper winding: Here, bar conductors are embedded in the outer periphery of the rotor poles and are short-circuited with the short-circuiting rings at both sides. The machine is started as a squirrel cage induction motor first. When it picks up speed, excitation is given to the rotor and the rotor starts rotating continuously as the rotor field is locked with stator revolving field.

11. Name the types of motors used in vacuum cleaners, phonographic appliances, vending machines, refrigerators, rolling mills, lathes, power factor improvement, and cranes.

Following motors are used: 
• Vacuum cleaners- Universal motor.
• Phonographic appliances – Hysteresis motor.
• Vending machines – Shaded pole motor.
• Refrigerators – Capacitor split phase motors.
• Rolling mills – Cumulative motors.
• Lathes – DC shunt motors.
• Power factor improvement – Synchronous motors.

12. State Thevenin’s Theorem:

According to Thevenin's theorem, the current flowing through a load resistance 
Connected across any two terminals of a linear active bilateral network are the ratio open circuit voltage (i.e. the voltage across the two terminals when RL is removed) and the sum of load resistance and internal resistance of the network. It is given by Voc / (Ri + RL).

13. State Norton’s Theorem

The Norton’s theorem explains the fact that there are two terminals and they are as follows:
• One is terminal active network containing voltage sources 
• Another is the resistance that is viewed from the output terminals. The output terminals are equivalent to the constant source of current and it allows giving the parallel resistance. 
The Norton’s theorem also explains about the constant current that is equal to the current of the short circuit placed across the terminals. The parallel resistance of the network can be viewed from the open circuit terminals when all the voltage and current sources are removed and replaced by the internal resistance.

14. State Maximum power transfer theorem

The Maximum power transfer theorem explains about the load that a resistance will extract from the network. This includes the maximum power of the network and in this case, the load resistance is being equal to the resistance of the network and it also allows the resistance to be equal to the resistance of the network. This resistance can be viewed by the output terminals and the energy sources can be removed by leaving the internal resistance behind.
