Designed and implemented a new cooling system for a manufacturing plant.
Researched different cooling technologies and their efficiency
Collaborated with a team of engineers to design the system layout
Performed simulations to optimize the cooling system performance
Managed the installation and testing of the new system
Design methodology is a systematic approach to solving engineering problems by following a series of steps.
Design methodology involves defining the problem, researching, brainstorming solutions, selecting the best solution, prototyping, testing, and refining.
It helps ensure that the final product meets the desired requirements and functions effectively.
Examples of design methodologies include Six Sigma, Lean Manufactur
The 3,2,1 principle of GD&T is a method used to establish a datum reference frame for geometric dimensioning and tolerancing.
3 points are used to establish a datum plane, 2 points to establish a datum line, and 1 point to establish a datum point.
The 3,2,1 principle ensures that the part is securely located and oriented in a consistent manner for measurement and manufacturing processes.
Datum features are used as referen...
I applied via Naukri.com and was interviewed in Aug 2024. There were 2 interview rounds.
Pattern features in Creo allow for creating repetitive geometry in a design.
Pattern features can be linear, circular, or mirror patterns.
Linear patterns create copies of a feature along a straight path.
Circular patterns create copies of a feature around a center point.
Mirror patterns create copies of a feature mirrored across a plane.
Pattern features help save time and maintain design consistency.
Family table in Creo allows for creating multiple variations of a part or assembly within a single file.
Family table is a feature in Creo Parametric that allows for creating multiple instances of a part or assembly with different dimensions or parameters.
It helps in managing different configurations of a design within a single file, reducing the need for multiple files for variations.
Users can define different values f...
I have 5 years of experience in mechanical engineering with a focus on designing and testing automotive components.
Designed and tested various automotive components such as suspension systems, engine parts, and cooling systems
Utilized CAD software to create detailed designs and simulations
Worked closely with manufacturing teams to ensure designs were feasible and cost-effective
Performed stress and thermal analysis on c...
Young's modulus is used in engineering to measure the stiffness of a material.
Young's modulus is used in stress-strain analysis to determine how much a material will deform under a certain load.
It is commonly used in structural engineering to design buildings, bridges, and other structures.
It is also used in material science to compare the mechanical properties of different materials.
Young's modulus is important in the...
Stress-strain curve shows relationship between stress applied to a material and resulting strain.
Stress-strain curve is a graphical representation of how a material deforms under stress.
It typically consists of a linear elastic region, yielding point, plastic deformation, and ultimate failure.
The slope of the curve in the elastic region represents the material's stiffness or Young's modulus.
The area under the curve rep...
Gap assessment is a process of evaluating the difference between current performance and desired performance.
Gap assessment involves identifying areas where performance falls short of expectations.
It helps in determining the steps needed to bridge the gap between current and desired performance.
Examples include assessing the skills gap in a workforce or evaluating the gap in compliance with industry standards.
HCLTech interview questions for designations
Tolerance zone for perpendicularity in GD&T is the allowable range within which a feature can deviate from being perfectly perpendicular.
Tolerance zone for perpendicularity is a 2D cylindrical tolerance zone that is perpendicular to a datum plane.
It is represented by two parallel planes that are a specified distance apart.
The feature must fall within this zone to be considered perpendicular.
The tolerance value specifie...

There are various types of joints used in mechanical engineering.
Welded joints - used for permanent joining of two metal parts
Bolted joints - used for temporary joining of two metal parts
Soldered joints - used for joining two metal parts with a filler metal
Riveted joints - used for joining two metal parts with a rivet
Adhesive joints - used for joining two metal parts with an adhesive material
Welding is a process of joining two or more metal parts by heating the surfaces to their melting points and allowing them to cool and fuse together.
Welding involves the use of heat and pressure to join two or more metal parts together
There are several types of welding processes including MIG, TIG, Stick, and Flux-Cored welding
Welding is commonly used in manufacturing, construction, and repair industries
Examples of weld...
What people are saying about HCLTech
I was interviewed in Dec 2016.
Low scores due to lack of time management and exam anxiety.
Struggled to allocate enough time for each question
Difficulty managing time during the exam
Anxiety affecting performance under pressure

I applied via Recruitment Consulltant and was interviewed before Feb 2021. There were 2 interview rounds.
Name mangling is a technique used by compilers to give unique names to functions and variables to avoid naming conflicts.
Name mangling is used in C++ to support function overloading.
It is also used in Python to avoid naming conflicts in modules.
Name mangling can make it difficult to access variables and functions from outside the class in which they are defined.
In C++, name mangling can be seen by using the 'nm' comman
