Want to hire C++ developers on your own? Here are the skills you must look for while hiring a C++ developer

Hiring C++ developers might be a complicated task for you if you are a non-technical manager. C++ is a widely-used programming language in the computer programming field, especially in graphics design, games development (because of its multiplayer support over a network), and developing database software. But, even if you belong to technical field, hiring C++ developers among thousands of developers is a challenging task for anyone. So, Ultragenius is here to assist you while hiring the top talented developers on your own. 

The following skills you must ensure while hiring a C++ developer – 

Steadfast knowledge of C++ library, containers, and algorithms

The C++ Standard Library (STL) is a collection of all C++ classes, data structures, algorithms, templates that are designed in C++. C++ STL can make your code more reusable, fast-working, and extensible. STL provides four types of components, namely, algorithms, functions, iterators, and containers. The C++ developers must know about Containers, Algorithms, Iterators, Container Adopters, Associative Containers, and Sequential Containers.

Experience writing code in C++

The C++ developer must have experience writing code in C++. C++, like Java and Python, has various functions, algorithms, and data structures that the C++ developer must be aware of. With the knowledge of its standard library, the C++ developer can code faster while maintaining the simplicity of code. Check if the C++ developer can code well in C++ and knows about its input-output stream (cout, cin), the difference between “\n” and endl, flush stream, use of cerr, etc.

Knowledge of Template coding

Templates are the powerful in-built feature of C++ which allows a programmer to write a generic algorithm that works with all kinds of data types and eliminates the requirement of writing different classes, functions, or some other code for different data types like integer, float, or string. It is also called Generic Programming.

Firm understanding of Object Oriented Programming Concepts

C++ is widely used as an Object Oriented Programming language. OOP helps to emulate real world entities. For example, if you want to design a messaging app, you have to first design a message class that contain all the information about sender,  message content, receiver, and message identity all inside a single class. The C++ developer must know about Encapsulation, Inheritance, Polymorphism, and Abstraction. Check whether the C++ developer knows about early or static binding, dynamic binding or late binding, various types of inheritance, etc. 

Experienced working with code versioning tools like Git, SVN, TFS

C++ developers must have a very good knowledge of version control systems, like Git, SVN, TFS, and Mercurial. Mostly, developers use Git for their work. It is the version control system that helps the team in collaborating and organizing your code, maintain the frequent changes that occur in the code. Git helps in reviewing the old codes and compares them with the newly updated code, pulling the code from their repository, and managing the commit history.

Along with this, the C++ developer must know how to use add, push, pull, and commit commands, how to do  branching, and merging as it allows developers to work independently on the code.

Excellent understanding of testing frameworks and tools

Rising quick-deployment needs during the development phase, testing has become a very important skill for developers to know. Check the C++ developers’ knowledge about Jest, Enzyme, Mocha, Chai, AVA, and Tape for unit testing.For end-to-end testing, check their knowledge about Selenium, Webdriver, Cucumber.js, Nightwatch.js, Cypress, and Puppeteer. For integration testing, ensure that the C++ developers know about Karma. 

Firm understanding of System Programming and Linux

The C++ developers write the code on Linux environment as it is an open source platform embedded with lots of C++ libraries and there are a lot of projects written in C++ for Linux/Unix operating system. The C++ developers must have firm understanding of setting up the environment, compiling, running, and debugging the code,  and installing different types of libraries.

Strong understanding of data structures and algorithms

Knowledge of data structures and algorithms enables a C++ developer write meaningful and concise code. You must ensure that the C++ developer developers you are hiring must know about popular algorithms like find, count, substr, finding minimum using min function, maximum using max function, and more. The C++ developers must know about map, set, vector, trees data structure.

Experience working with SQL and NoSQL databases

The C++ developers must know working with SQL and NoSQL databases.. The C++ developer must be familiar with the fundamental concepts of DBMS like data integrity, data access control, automatic rollback, restart and recovery. The developers must know DDL, DML, DCL, TCL, and DQL commands.  Check if the C++ developer is well-versed with  about Normalization, E-R Model, ORM Mapping, and Joins.

Knowledge of HTML and CSS

HTML (Hypertext Markup Language) and CSS (Cascading Style Sheets) are the two must-know technologies for any developer. For any kind of application development, knowledge of these two core  technologies helps. You must hire a C++ developer who has basic understanding of HTML  and CSS.   

Experienced with Software Configuration Management (SCM)

The developers must know about Software Configuration Management. Software Configuration Management (SCM) is the process of identifying, tracking, and controlling the changes in the software. The SCM activities are important for a C++ developer to know. SCM helps developers to track and handle the products and its different versions. It identifies and controls the software configuration, hardware, and tools that are involved in the software development process.

Connect with the top 1% C++ developers of the world at the lowest prices

C++ is robust language used in developing desktop and mobile applications. It is very fast because of which it is used in developing game engines and variety of games. C++ provides different paradigms of programming like procedural, object-oriented, imperative, and declarative. But recruiting the best C++ developers is not an easy task when a large no. of C++ developers are competing to grab the job opportunities.  

Top Interview Questions to ask while hiring a C++ developer

  • The reference variable once assigned cannot be reassigned with different values while the pointer variable acts independently of assigning values and can be reassigned pointing to different variables.
  • A pointer variable can be assigned NULL values while a reference variable cannot.
  • A reference variable is compulsorily initialized at the time of declaration while it is not necessary to initialize the pointer variable at the time of declaration.
  • The pointer requires an indirection operator to access the value while the reference value can be accessed directly.
  • The reference variable is a type of alias for the existing variable while the pointer variable stores the address of a variable.

A friend function is a function which is specified outside a class but can access the private, protected, and public members of that class. Friend functions are only used for specific purpose and is avoided normally. 

The main characteristics of a friend function is - 

  • Friend functions are outside the scope of the class in which they are declared.
  • As the friend function is outside the scope of a class, it is invoked without creating a object of that class.
  • A friend function cannot directly access the private members of a class, it needs to use an object name with dot operator to access them.
  • Friend functions take objects as arguments.


Function Overloading provides more than one definition of any function. The difference can be in the number of parameters and the type of parameters. For example, 

  • double add(int a, float b)
  • double add (float a, int b)
  • double add (double a, double b, double c)

Function Overriding means the object created at run-time decides which function has to be invoked if the reference is of parent class. 


The four pillars of Object-Oriented Programming is -

  • Encapsulation - Encapsulation is the ability of a class to hide its data variables and avoids its direct access. Encapsulation is achieved by invoking getter() and setter() functions on an object to access a data variable.
  • Inheritance - Inheritance is the mechanism of a class to extend the functionality of another class. It provides the advantage of code reusability to the freelance C++ developers.
  • Abstraction - Abstraction is the process of hiding the implementation details of any class and showing only the necessary or required details to a user. Abstract classes and Interfaces best uses the concept of Abstraction.
  • Polymorphism - Polymorphism is the ability of a fucntion to take many forms. Polymorphism is of two types - Compile-time Polymorphism and Run-time Polymorphism.  In Compile-time Polymorphism, the function call is decided at the compile-time only. Among the functions with the same name, the invocation is decided based on  number of parameters and type of parameters. It implements Function Overloading.  In Run-Time Polymorphism, the object of the child class decides which method to invoke at the run-time. It implements Function Overriding. 

using namespace std is the scope in which class names, function names, and variable names are defined. C++ contains the in-built classes, libraries, and functions that the freelance C++ developers use in designing applications.

A virtual function is a member of the base class which is overridden in the derived class. The virtual function in base class needs to be overridden in the child class. Virtual functions implement Run-time Polymorphism. In the derived class, the object created at the run-time decides whether the virtual function of base class is invoked or the overridden function of derived class is invoked using base class pointer.

Run-time polymorphism can be achieved without using virtual functions by type-casting the base class pointer to the derived class pointer and then calling the function. 

For example, 

class Base{

void func(){}


class Derived : public Base{

void func(){



int main(){

Base* ob = new Derived;

Derived* d = static_cast<Derived*>(ob);


  • A structure groups various data types which are called by the same name while a class binds the data variables and member functions inside a single structure. 
  • Classes support inheritance while structures don't support inheritance.
  • A structure occupies memory on the 

Functions that are declared as static in the base class cannot be overridden in the derived class because they are not affected by the object creation. However, static functions can be overloaded 

Destructors are the member functions in a class used to delete objects when they go out of class scope, function ends, program ends, and the delete keyword is called to deallocate the memory of an object. The destructors are different from normal member functions because neither they take arguments nor they return anything. For example, 

class Test{

int a,b;


public Test(int a, int b){

cout<<"Inside Constructors\n";

this.a = a;

this.b = b;


void show(){

cout<<a<<" " <<b<<endl;



cout<<"Inside Destructor\n";


int main(){

Test obj(10,20);;

return 0;


The output of the program is  - 

Inside Constructor

10 20 

Inside Destructor
