ENGINEERING Interview Questions And Answers! (How To PASS an Engineer Interview!)

Explain how hydraulics work on a machine

Using a incompressible fluid machines use hydraulics to transmit force from one point to another. In most cases, this increases the force applied at one end for a given amount of effort.

Describe the difference between a tube and a pipe

Pipes are always round while tubes can come in different shapes such as rectangular, square, or cylindrical.

A pressure force is evenly distributed due to the circular shape of a pipe.

Outside diameter (OD) and wall thickness (WT) are used to measure a tube.

Do you prefer working alone or with an engineering team?

This mechanical engineering interview question can help determine if they work well with teams or are perhaps better suited for solo type projects and work.

What mechanical engineering tasks interest you?

The only bad answer is saying “Any task”. Every engineer has engineering tasks they prefer over others, like solving equations, design engineering, building prototypes, testing, engineering analysis, or communicating the design.

This question gives you a chance to see if the main tasks the job calls for are ones the engineer enjoys doing.

An elastomer is a polymer when its percentage elongation rate is?

Fatigue is the reduced tendency of a material to offer resistance to applied stress under repeated or fluctuating loading conditions.

Creep is low and progressive deformation of a material with time under constant stress at high-temperature applications.

What is the difference between a strut and a column?

A Column is always vertical but a strut could carry an axial compressive load in any direction. A strut and column both carry the compressive load.

Name an engineering skill have you learned recently?

Good engineers are interested in learning new skills, computer programs, and ways to solve problems. Listen carefully to what the interviewee says to see if they have a love of learning new things and are adaptable to various situations.

What is the process flow diagram?

A process flow diagram is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment.

Using an artificial heat exchange system mechanical refrigeration is a process where heated is removed from a chosen location.

This refrigeration system can be thermoelectric, magnetic, non-cyclic, cyclic, and will depend on the refrigeration application needed.

What is the most difficult project you have worked on, and how did you get through the challenging tasks?

Engineers often work on complex and tasking projects that involve multiple resources, timelines and teams. Your response to this question can show you can multitask and manage your time well. Make sure you thoroughly explain your thought processes for overcoming challenges and the practical ways you used your skills to get through the adverse conditions. If you have any first-hand experience with challenging engineering situations, offer to describe that too.

Example: “I once worked on an engineering project that involved developing predictions about mountains and the roadways near them. I changed the data that I was used to working with to include any climate or environmental changes, as the risk factors changed based on the wildlife, the weather and the people in that area. With these adaptations, I was able to complete the project despite how challenging I thought it was in the beginning.”
