Tip 2: Highlight the time you improved from a loss you faced in your job
Answer: I have failed a couple of times in my career. However, the most notable one happened once during my first time working with heavy machinery, I didn’t take a complete system checkup before using it. That led to a system failure as a bolt was loose in it. This crashed the whole machinery and also delayed the project we were working on. After this incident, I have worked harder and have always performed my security checks before working on anything.
11. What Do You Mean by Cotter Joint?
Tip 1: The interviewer wants to know if you understand the basic terms of engineering.
Tip 2: Show the interviewer that you are heavily knowledgeable.
It is a joint utilized to connect two rods under the compressive or tensile stress. This joint is composed of iron or steel. It combines the piston rod to the crosshead of the reciprocating steam engine.
12. What Is the Benefit of The Hydraulic Brake Compared To Mechanical Brake And Electric Brake
Tip 1: The interviewer is trying to assess if you have a basic understanding of engineering concepts.
Tip 2: Show that you are knowledgeable.
Answer: Hydraulic brakes work devoid of brake cables. For mechanical brakes, you have to pull the brake lever, which in turn pulls the brake caliper that reconnects the brake pads back to the rim.
13. What Are the Different Cold Drawing Processes?
Tip 1: The interviewer is assessing whether you are good at your job and understand certain basic principles in your field.
Tip 2: Show that you are an expert.
Answer: Cold drawing process reduces the diameter in the cross-section of tubes or the wires by drawing through the successively smaller dies without heating the material previously, increasing the tensile strength. This process makes steel wires for prestressing.
The cold drawing process of steel bars and wires include:
– The raw stock: Hot rolled steel bars or rod coils are used as the raw material
– Cleaning: The abrasive scales over the surface made of the hot-rolled rough stock is hence removed
14. Mention the First Thing You Ever Designed
Tip 1: The interviewer wants to know if you are creative enough.
Tip 2: Mention your first-ever designed object and make it impressive.
Answer: When I was a kid, I designed a very functional toy car with a steering system. I spent many weeks on it, tried figuring out how to make an axle, and getting the vehicle to turn right. I also used little pieces from other toy cars and screws I found from around the house.
15. How Would You Best Explain the Car’s Wheel and Axle System to Any Layperson?
Tip 1: The interviewer wants to know if you are a good communicator.
Tip 2: Show him your willingness to break complex issues and not being frustrated
Answer: I would explain this by saying that the Axles serve two primary purposes. They bear some car weight and help the steering system turn your wheels. So when you turn your steering wheels to the right, the axle helps rotate the tires and absorbs the weight shift.
16. Why Do Customers Buy Any Product?
Tip 1: The interviewer wants to know if you understand what strikes an interest in customers and whether you can tailor your design in such a way.
Tip 2: Also, show that you have an understanding of the market.
Answer: A customer buys a product only if it would help make his/her life better. People want value for their money, and therefore, products should be made to convince them that their money does not go to waste.
17. What Do You Like About Working In A-Team?
Tip 1: The interviewer would like to know if you can fit in a team.
Tip 2: Show that you are willing to accept any feedback from the teams in the company

Tip 2: Show the interviewer that you came well prepared and are a master of your game.
Answer: Annealing is the process of shortly heating any material above the temperature of recrystallization and cooling. This process boosts the hardness and strength of metal material, resulting in the reduction of dislocations in the crystal structure of the metal is annealed.
20. Explain Uniformly Distributed Load?
Tip 1: How good are you in this field? The interviewer would like to know.
Tip 2: Convince the interviewer that you understand everything that this job entails.
