I applied via Naukri.com and was interviewed in Mar 2022. There were 3 interview rounds.
Questions related to c++ concepts like templates, copy constructor and inheritance. Questions related to pointers.
Inheritance is a concept in object-oriented programming where a class inherits properties and behaviors from another class.
Inheritance allows code reuse and promotes code organization.
There are different types of inheritance: single, multiple, multilevel, hierarchical, and hybrid.
Single inheritance involves a class inheriting from a single base class.
Multiple inheritance involves a class inheriting from multiple base c...
Constructors and destructors are special member functions in object-oriented programming languages.
Constructors are used to initialize the object's data members when it is created.
Destructors are used to free up any resources allocated by the object when it is destroyed.
Constructors have the same name as the class and no return type.
Destructors have the same name as the class preceded by a tilde (~) and no return type.

Copy constructor creates a new object by copying an existing object of the same class.
Copy constructor is used to create a new object with the same values as an existing object.
It takes an object of the same class as a parameter.
It is different from regular constructors as it creates a new object by copying an existing object.
Copy constructor is invoked when an object is passed by value or returned by value.
Virtual functions allow polymorphism, abstract classes cannot be instantiated, pure virtual functions have no implementation.
Virtual functions are functions in a base class that can be overridden in derived classes
Abstract classes are classes that have at least one pure virtual function and cannot be instantiated
Pure virtual functions have no implementation and must be overridden in derived classes
Virtual functions can...
Copy constructor creates a new object by copying an existing object, while = operator assigns the value of one object to another.
Copy constructor is used to create a new object with the same values as an existing object.
= operator is used to assign the value of one object to another.
Copy constructor is invoked when a new object is created from an existing object.
= operator is invoked when an existing object is assigned...
Lambda functions are anonymous functions that can be passed as arguments or stored in variables.
Lambda functions are also known as anonymous functions or closures.
They are commonly used in functional programming languages like Python and JavaScript.
Lambda functions can be used to create higher-order functions, which take other functions as arguments.
They are often used for filtering, mapping, and reducing data in colle...

Simple embedded c coding round
I applied via LinkedIn and was interviewed before Sep 2022. There were 3 interview rounds.
Normal Aptitude test for 1 hour
To reverse an array of strings, iterate through the array and swap elements from start to end.
Iterate through the array using two pointers, one starting from the beginning and the other from the end.
Swap elements at the two pointers until they meet in the middle.
Repeat until all elements are swapped and the array is reversed.
I applied via Job Fair and was interviewed before Oct 2022. There were 3 interview rounds.
OOPS focuses on objects and classes, while functional programming focuses on functions as first-class citizens.
OOPS involves concepts like inheritance, encapsulation, and polymorphism.
Functional programming emphasizes immutability, pure functions, and higher-order functions.
In OOPS, data is typically stored in objects with methods to manipulate the data.
Functional programming avoids side effects and mutable state.
Examp...
There was simple aptitude questions along with some C snippet
RISC (Reduced Instruction Set Computing) has a smaller set of simple instructions, while CISC (Complex Instruction Set Computing) has a larger set of complex instructions.
RISC processors have simpler instructions that can be executed in a single clock cycle, making them faster.
CISC processors have more complex instructions that may require multiple clock cycles to execute.
RISC architectures typically have a smaller chi...
ADC converts analog signals into digital data by sampling the input signal at regular intervals.
ADC samples the input signal at regular intervals
It quantizes the sampled values into discrete digital values
The resolution of ADC determines the number of possible digital values
Common types of ADC include successive approximation ADC and delta-sigma ADC
