Faurecia Software Engineer Interview Questions and Answers

Design patterns in C++ are reusable solutions to common problems in software design.

• Design patterns help in creating flexible, maintainable, and scalable code.

• Examples of design patterns in C++ include Singleton, Factory, Observer, and Strategy.

• Each design pattern has its own purpose and can be applied in different scenarios.

• Understanding design patterns can improve code quality and efficiency.

A virtual function is a member function in a base class that can be overridden in derived classes, enabling polymorphism.

• Enables dynamic binding, allowing the program to decide at runtime which function to call.

• Declared using the keyword 'virtual' in the base class.

• Example: In a base class 'Shape', a virtual function 'draw()' can be overridden in derived classes like 'Circle' and 'Square'.

• Supports polymorphism, allowin...read more

Polymorphism allows objects to be treated as instances of their parent class, enabling method overriding and overloading.

• Types of polymorphism: compile-time (method overloading) and runtime (method overriding).

• Example of method overloading: multiple functions with the same name but different parameters.

• Example of method overriding: a subclass providing a specific implementation of a method defined in its superclass.

Preprocessing raw data involves cleaning, transforming, and organizing data to make it suitable for analysis.

• Remove any irrelevant or duplicate data

• Handle missing values by imputation or deletion

• Normalize or standardize numerical data

• Encode categorical variables using techniques like one-hot encoding

• Feature scaling for machine learning algorithms

• Perform text preprocessing like tokenization and stemming

Specify the existing solution by documenting its architecture, components, technologies used, and any modifications made.

• Document the architecture of the solution, including high-level components and their interactions

• List the technologies used in the solution, such as programming languages, frameworks, and databases

• Describe any modifications or customizations made to the existing solution

• Include any performance metric...read more
