Metexim Sourcing Interview Questions and Answers

Flushing is the process of cleaning out a system by forcing fluid through it, while cavitation is the formation of vapor bubbles in a liquid due to rapid changes in pressure.

• Flushing involves using a fluid to remove contaminants or debris from a system, such as a hydraulic system or a pipeline.

• Cavitation occurs when the pressure in a liquid drops below its vapor pressure, causing bubbles to form and collapse, leading t...read more

Materials come in different grades based on their composition, properties, and intended use.

• Materials can be classified into metals, polymers, ceramics, and composites.

• Each material type has different grades based on factors like strength, durability, conductivity, and corrosion resistance.

• Examples include steel grades like 304, 316, and 430, polymer grades like HDPE and PVC, and ceramic grades like alumina and zirconi

Stress is the force applied to a material, while strain is the resulting deformation. Mild steel has a linear stress-strain curve.

• Stress is the force applied to a material per unit area, measured in N/m^2 or Pascals.

• Strain is the resulting deformation of the material, measured as a ratio of the change in length to the original length.

• Mild steel typically has a linear stress-strain curve until it reaches its yield point...read more

Material properties refer to the physical and chemical characteristics of a substance.

• Material properties include mechanical properties (e.g. strength, hardness), thermal properties (e.g. conductivity, expansion), electrical properties (e.g. resistivity, conductivity), and chemical properties (e.g. reactivity, corrosion resistance).

• Mechanical properties describe how a material responds to applied forces, such as tensil...read more

Strength of materials is a branch of engineering that deals with the behavior of solid objects subjected to stresses and strains.

• Strength of materials is concerned with the study of how materials deform and fail under various loads.

• It involves analyzing the mechanical properties of materials such as stress, strain, elasticity, and plasticity.

• Understanding the strength of materials is crucial in designing and constructi...read more

A diesel engine is an internal combustion engine that uses compression ignition to burn fuel.

• Diesel engines are more fuel efficient than gasoline engines.

• They are commonly used in trucks, buses, and heavy machinery.

• Diesel engines do not have spark plugs; instead, they rely on compression to ignite the fuel.

• They produce more torque at lower RPMs compared to gasoline engines.

• Diesel engines are known for their durability

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Transformers are used to increase or decrease voltage levels in electrical circuits.

• They consist of two coils of wire, known as the primary and secondary coils, wrapped around a core made of ferromagnetic material.

• Transformers are essential in power distribution systems to step up voltag...read more

I handle job pressure by prioritizing tasks, staying organized, seeking support when needed, and taking breaks to recharge.

• Prioritize tasks based on deadlines and importance

• Stay organized by creating to-do lists and setting realistic goals

• Seek support from colleagues or supervisors when feeling overwhelmed

• Take short breaks to recharge and refocus

Yes, I am comfortable with field service engineer roles.

• I have experience working in field service roles in the past

• I enjoy hands-on work and problem-solving in real-world situations

• I am willing to travel and work in various locations as needed

DFMEA stands for Design Failure Mode and Effects Analysis, while DFMA stands for Design for Manufacturability and Assembly.

• DFMEA is a systematic approach to identifying and preventing potential failure modes in a design.

• DFMEA involves analyzing each component of a design to determine potential failure modes, their effects, and the likelihood of occurrence.

• DFMA focuses on designing products that are easy to manufacture ...read more

Design procedures are systematic steps followed to create a product or system.

• Design procedures involve defining requirements and constraints.

• They include brainstorming, concept development, prototyping, testing, and refining.

• Documentation of the design process is essential for future reference.

• Examples include the design procedures followed in creating a new software application or a mechanical device.
