Top 30 Engineering Interview Questions (Freshers/Experienced) 2023

There is no doubt that engineering has become one of the most common fields and more and more people are choosing it as their major and career path. Well, given the need for engineers in the developing economies as well as the technology of the world, the choice seems fair. But the thing is, there are so many people with engineering degrees that the jobs seem less compared to the candidates and that is why when it comes to engineering interviews, you would be up against many candidates. Which makes it difficult to get the job unless you prove yourself as the best among others.
That is where the interview seems like a big deal and if you get through the interview part you must prepare yourself for that. To do that you have to brush up on your knowledge about the topics and what have you learned so far. But that’s not going to be enough, you must prepare the most asked questions as well. See, there are a few questions are that most frequently asked in the engineering interview. These questions would have a higher probability of being asked in the interview and if you have prepared them, you would have an upper hand as well.
Overall, what you need to be aware of, is the fact there would be some mostly asked engineering interview questions that you need to be worried about. But first of all, you need to find these questions. Where would you find the most asked engineering interview questions? Well in our article, after all, that’s why you are here right? You will not be disappointed with our article, because we have included some of the best engineering interview questions to know about.
So let’s move ahead and take a look at the following engineering interview questions so that you can prepare for the interview.

Engineering interview questions

Q11.When did you start your job search? Have you been offered any positions?
Be relaxed and explain that you are looking for a company and role with the right fit, and that you are quite choosy when it comes to finding the ‘right job’. You may then need to answer what you believe the ‘right job’ entails.
Q12.What do you enjoy most/least about engineering?
You should tailor this to the responsibilities of the role you are interviewing for and try to keep your answer centred on the positives.
Q13.Where do you see yourself ten years from now?
You should research a career path that would flow from the position for which you are interviewing and ensure that you emphasise the intention to master the demands of that position first.
Q14.What would you consider to be your greatest success in using your skills to solve an engineering problem?
Draw upon a specific example – one that showcases your strengths as an engineer, such as the ability to think on your feet.
Q15.What new engineering specialty skills have you developed during the past year?
Detail any particular skills that you developed whilst at university and describe how you obtained them. Finish up talking about your willingness to learn.
Q16.What do you get out of engineering that you couldn’t get from any other kind of work?
You could talk about one engineering achievement that you are especially proud of, or you could explain how day-to-day aspects of the work stimulate you. If it is the latter, you should again tailor this to the role for which you are interviewing.
Q17.On your last project assignment, what problems did you identify that had been previously overlooked?
This is an ideal opportunity to depict several key qualities such as attention to detail, effective communication and creative thinking. You should come to the interview prepared with an example.
Q18.What was the workload like in your previous engineering department?
It is imperative that you do not complain about the workload in your previous job, even if it was taxing. Illustrate your efficiency; explain how you manage your time and prioritise tasks.
Q19.What personal characteristics do you feel are necessary to be a successful engineer?
Choose three or four characteristics and expand on why you think they’re important. You could also describe how a previous manager of yours displayed these qualities to good effect and how you learned from that example.
Q20.Describe an experience with a difficult client. How did you handle the situation?
Your answer should include: the way you listened to what the client had to say, confirmed an understanding of their concerns and subsequently took responsibility to resolve the situation by offering a solution, without going into too much detail about the specific complaint.

Mechanical engineering interview questions and answers

Q21.How Can You Convert Air Mass To Air Volume?
Mass = density * volume.
Air density is p/RT, where R is the gas constant for air (287 J/kg-K), T is the absolute temperature, and p is the pressure, equal to 101325 Pa at sea level.
At sea level and room temperature, the density of air is rho 101325 N/m2/ (287 N-m/ (kg-K)*293 K or about a) 2 kg/mc)
Q22.What Are Different Types Of Gate Valves?
There are a few different designs:
Parallel disk gate valves use two disks with a spring in between them, sliding into the seats. At low pressure, the spring forces the disks outward against the seats, sealing off the valve. At high pressure, all the sealing is accomplished by the downstream disk.
Wedge gate valves use a tapered disk that slides into two seats set at a slight, converging angle. The wedging action provides the sealing force between the disk and the seat.
Single disk gate valves are used where the flow is always one-way (like sluices on dams). There is some flexibility in the attachment of the disk to the stem, so the differential pressure on the disk pushes it against the seat, sealing it off.
Q23.What Is The Density Of Plastic?
Plastics are the general term for a wide range of synthetic or semisynthetic polymerization products. There are many different plastics; all have their own density!
Most common plastics, however, have a density between .035 and .045 lb/cu in.
Q24.What Is An Ortographic Drawing?
Orthographic projections are views of a 3D object, showing 3 faces of it. The 3 drawings are aligned so that if the page were folded, it would create part of the shape. It is also called multiview projections.
The 3 faces of an object consist of its plan view, front view and side view. There are 2 types of orthographic projection, which are 1st angle projection and 3rd angle projection.
Q25.How Do Concrete Pumps Work?
liquid (fluid) concrete has a big viscosity, how the pump overcomes this big viscosity.  every couple seconds maybe 4-5 seconds the machine emits a loud thump. sound come from pnomatic part of the machine.
Q26.What Is Representative Elementary Volume?
Smallest volume over which measurements can be made that will yield a representative of the whole.
Q27.What Does A Rolling Offset Look Like?
Rolling offsets are used in the piping and sheet metal (ductwork) trades, a rolling offset changes the elevation and locaton of the piping or duct usually by using two fittings to offset around obstacles. Rolling offsets are used mostly when you are limited to the size of the fittings in order to change your elevation and location.
Q28.What Kind Of Paper Airplane Flies The Farthest?
Thickest paper has the greatest mass and therefore potential energy. Potential energy equals kinetic energy (speed). Speed equals lift. Lift equals a greater flight distance. Thicker planes fly farther.
Q29.How Does An Equal-arm Balance Work?
Two pans of equal balances are placed at the end of the beam, one at each end. A long pointer attached at right angles to the beam at the point of support. Zero on a scale indicates the beam is at rest.
Q30.Can You Use Motor Oil In A Hydraulic System?
Hydraulic fluid has to pass a different set of standards than motor oil. Motor oil has tackifiers, lower sulfur content, and other ingredients that could prove harmful to the seals and other components in a hydraulic system. If it is an emergency only should you do it.
Q31.What Does Angular Momentum Mean?
Angular momentum is an expression of an objects mass and rotational speed.
Momentum is the velocity of an object times it is mass, or how fast something is moving how much it weigh. Therefore, angular momentum is the objects mass times the angular velocity where angular velocity is how fast something is rotating expressed in terms like revolutions per minute or radians per second or degrees per second.
Q32.What Is The Role Of Nitrogen In Welding?
Nitrogen is used to prevent porosity in the welding member by preventing oxygen and air from entering the molten metal during the welding process. Other gases are also used for this purpose such as Argon, Helium, Carbon Dioxide, and the gases given off when the flux burns away during SMAW (stick) welding.
Q33.What Causes White Smoke In Two Stroke Locomotive Engines?
That is the engine running too lean (lack of fuel). This condition will lead to overheating and failure of the engine.


So these are some of the best and some of the most asked engineering interview questions that you need to know about.
