Qualcomm Interview Questions, Process, and Tips

Q1. What is virtual function?
Ans. 
A virtual function is a function in a base class that is declared using the keyword 'virtual' and can be overridden by a function in a derived class.
• Virtual functions allow a derived class to provide a specific implementation of a function that is already defined in a base class.

• They enable polymorphism, where a pointer to a base class can be used to call a function in a derived class.

• Virtual functions are used in obje...read more

Q4. What is inheritance
Ans. 
Inheritance is a concept in object-oriented programming where a class inherits properties and behaviors from another class.
• Allows for code reusability by creating a new class based on an existing class

• Derived class (subclass) inherits attributes and methods from a base class (superclass)

• Can have multiple levels of inheritance (multi-level inheritance)

• Example: Animal class can be a base class with properties like name a...read more

Q5. What is polymorphism
Ans. 
Polymorphism is the ability of a single function or method to operate on different types of data.
• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• It enables a single interface to be used for different data types.

• Examples include method overloading and method overriding in object-oriented programming.

Q2. Explain CAP theorem.
Ans. 
CAP theorem states that in a distributed system, it is impossible to simultaneously guarantee consistency, availability, and partition tolerance.
• Consistency: All nodes in the system have the same data at the same time.

• Availability: Every request gets a response, even if some nodes are down.

• Partition Tolerance: The system continues to operate despite network partitions.

• In a distributed system, you can only achieve two o...read more
