I applied via Campus Placement and was interviewed before May 2020. There were 4 interview rounds.
HashMap is a data structure that stores key-value pairs and provides constant time complexity for basic operations.
HashMap uses hashing to store and retrieve values based on their keys.
It allows null values and one null key.
Collisions are resolved by chaining or open addressing.
The initial capacity and load factor can be specified during initialization.
The internal array is resized when the load factor exceeds a thresh...
StringBuffer is synchronized while StringBuilder is not.
StringBuffer is thread-safe while StringBuilder is not.
StringBuffer is slower than StringBuilder due to synchronization.
StringBuilder is preferred for single-threaded operations.
Both classes are used for manipulating strings.
Example: StringBuffer sb = new StringBuffer(); StringBuilder sb = new StringBuilder();
The entry point of a Java program, must be public, static, void and accept an array of strings as argument.
public: accessible from anywhere in the program
static: belongs to the class, not to an instance of the class
void: does not return any value
main: the name of the method that serves as the entry point of the program
String[] args: an array of strings that can be used to pass arguments to the program
A thread is a lightweight process that can run concurrently with other threads within a program.
Threads share the same memory space as the parent process.
Threads can communicate with each other through shared memory.
Threads can be created and managed using threading libraries in programming languages like Java and Python.
Encapsulation is the process of hiding implementation details and exposing only necessary information.
Encapsulation is achieved through access modifiers like public, private, and protected.
It helps in achieving data abstraction and information hiding.
It prevents unauthorized access to the internal details of an object.
Example: A class with private variables and public methods to access those variables.
Example: A capsul...
Fill ratio is the percentage of array slots that are occupied by elements. Concurrency level is the estimated number of concurrently updating threads.
Fill ratio is important for performance optimization and memory usage.
Concurrency level determines the number of segments in the collection.
Higher concurrency level can improve performance but also increases memory usage.
Examples of concurrent collection frameworks includ

I applied via Naukri.com and was interviewed before Jul 2020. There was 1 interview round.
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
I applied via Naukri.com and was interviewed in Aug 2020. There were 3 interview rounds.
Abstract Factory is a creational design pattern that provides an interface for creating families of related objects.
Abstract Factory is used when we need to create families of related objects without specifying their concrete classes.
It provides an interface for creating objects of related classes without specifying their concrete classes.
It encapsulates a group of factories that have a common theme.
It promotes loose c...
Range based map iteration can be done using a for-each loop or iterators.
Use a for-each loop to iterate over the map elements.
Alternatively, use iterators to traverse the map.
The range-based for loop is preferred for its simplicity and readability.
Example: for(auto const& [key, value] : myMap) { //do something with key and value }
Detached threads are independent threads that run separately from the main thread. Joined threads are threads that wait for the main thread to finish.
Detached threads are created using pthread_detach() function
Joined threads are created using pthread_join() function
Detached threads do not need to be explicitly terminated
Joined threads must be explicitly terminated using pthread_exit() or return statement
Detached thread...
Static code analysis tools are software programs that analyze source code to find potential issues and improve code quality.
Static code analysis tools scan code without executing it
They can detect issues such as security vulnerabilities, coding errors, and performance problems
Examples of static code analysis tools include SonarQube, ESLint, and Checkstyle
Command to list currently running threads in linux
Use the 'ps' command with the 'H' option to display threads in a hierarchy
Use the 'top' command to display threads in real-time
Use the 'htop' command for an interactive display of threads
No, arithmetic operations cannot be performed on unique pointers.
Unique pointers are used to manage the lifetime of dynamically allocated objects.
They cannot be copied or assigned, only moved.
Arithmetic operations are not defined for pointers, including unique pointers.
Designing Facebook is a complex task involving various components and technologies.
Identify the core features of Facebook such as user profiles, news feed, messaging, and groups.
Choose appropriate technologies for each component such as PHP for backend, React for frontend, and MySQL for database.
Ensure scalability and performance by implementing caching, load balancing, and database sharding.
Implement security measures...
