10+ Executive Engineer Interview Questions and Answers for Freshers

The tests for concrete and steel include cube test for concrete and tensile test for steel. If the cube test fails, additional tests like rebound hammer test or ultrasonic pulse velocity test can be performed.

• Concrete test: Cube test is performed to determine the compressive strength of concrete. A cube specimen is prepared and subjected to compressive load.

• Steel test: Tensile test is conducted to measure the strength and ductility of steel. A steel specimen is subjected to t...read more

The amount of square metres of shuttering done in a day by 1 carpenter and 1 helper varies based on factors like experience, efficiency, and complexity of the task.

• The square metres of shuttering done per day can range from 10-50 depending on the skill level and speed of the carpenter and helper.

• Factors such as the type of material used, complexity of the design, and availability of tools can also impact the amount of shuttering done in a day.

• For example, a highly skilled car...read more

Nominal mix is a rough mix with fixed ratios, while design mix is a specific mix designed for a particular strength and durability.

• Nominal mix has fixed ratios like 1:2:4, while design mix is calculated based on specific requirements.

• Design mix is more precise and tailored to achieve desired strength and durability.

• Nominal mix is commonly used for small construction projects, while design mix is preferred for larger projects.

• Example: Nominal mix - 1:2:4 for concrete, Design m...read more

Implement mistake-proofing techniques to prevent repetitive problems.

• Identify the root cause of the problem

• Design a poka-yoke that prevents the mistake from happening

• Test the poka-yoke to ensure it is effective

• Train employees on the new process

• Continuously monitor and improve the poka-yoke

• Examples: color-coding, checklists, sensors, warning lights

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

• Ohm's law is represented by the equation V=IR, where V is voltage, I is current, and R is resistance.

• It is used to calculate the current flowing through a circuit given the voltage and resistance.

• The law is named after Georg Simon Ohm, a German physicist.

• The law is applicable to both AC and DC circuits.

Reputable problems can be tackled by identifying the root cause and implementing effective solutions.

• Conduct a thorough analysis to identify the root cause of the problem

• Develop a plan of action to address the issue

• Implement the plan and monitor progress

• Communicate with stakeholders to keep them informed

• Evaluate the effectiveness of the solution and make adjustments as necessary

PID controller is a type of control loop feedback mechanism used in systems to control the output based on the error between the desired setpoint and the actual process value.

• PID stands for Proportional, Integral, Derivative.

• Proportional term responds to the current error value.

• Integral term responds to the accumulation of past errors.

• Derivative term responds to the rate at which the error is changing.

• Used in various applications like temperature control, speed control, robot...read more

Syphon effect is the flow of liquid from a higher level to a lower level through a tube due to atmospheric pressure.

• It occurs due to the difference in pressure between the two ends of the tube.

• The liquid flows from the higher level to the lower level until the pressure is equalized.

• It is commonly used in aquariums, toilets, and irrigation systems.

• The syphon effect can also be used to transfer liquids from one container to another without the need for a pump.

Stress strain curve is a graphical representation of the relationship between stress and strain of a material.

• It shows how a material deforms under stress

• It helps in determining the strength and ductility of a material

• It consists of two parts: elastic region and plastic region

• Elastic region shows the linear relationship between stress and strain

• Plastic region shows the non-linear relationship between stress and strain

• Examples of stress strain curves include tensile, compressi...read more

Bending is the process of deforming a material along a straight axis, while forming is the process of shaping a material into a desired form.

• Bending involves applying force to a material to change its shape along a single axis.

• Forming involves shaping a material into a desired form, which may involve bending as one of the steps.

• Bending is often used in metalworking to create angles or curves in a piece of metal.

• Forming can include processes like stamping, forging, or rolling ...read more

Firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules.

• Firewall acts as a barrier between a trusted internal network and untrusted external network.

• It can be implemented in hardware, software, or a combination of both.

• Firewalls can filter traffic based on IP addresses, port numbers, protocols, and other criteria.

• Examples of firewalls include Cisco ASA, Palo Alto Networks, and pfSense.

Active Directory (AD) is a directory service used by organizations to manage and secure resources such as computers, users, and groups.

• Centralized management of network resources

• Authentication and authorization of users and computers

• Group policy management for enforcing security settings

• Single sign-on for users to access multiple resources

• Integration with other services like DNS and DHCP

• Example: Creating user accounts, assigning permissions, managing group policies

Some of the most trending antivirus software currently include Bitdefender, Norton, and Kaspersky.

• Bitdefender

• Norton
