Cognizant Program Analyst Interview Questions, Process, and Tips

Object-oriented programming concepts include encapsulation, inheritance, and polymorphism.

• Encapsulation: Bundling data and methods together in a class to hide implementation details.

• Inheritance: Creating new classes from existing ones, inheriting their properties and behaviors.

• Polymorphism: Objects of different classes can be treated as objects of a common superclass.

• Example: Encapsulation - A class 'Car' with private ...read more

Developed a project management tool for tracking and analyzing project progress.

• Implemented features such as task assignment, progress tracking, and reporting.

• Integrated with third-party APIs for data synchronization and collaboration.

• Utilized agile methodologies for iterative development and continuous improvement.

Network security refers to the practice of protecting computer networks from unauthorized access or attacks.

• Network security involves implementing various measures to prevent unauthorized access to a network, such as firewalls, intrusion detection systems, and virtual private networks (VPNs).

• It also includes ensuring the confidentiality, integrity, and availability of data transmitted over the network.

• Examples of netwo...read more

Paging and Segmentation are memory management techniques used by operating systems.

• Paging divides memory into fixed-size pages and stores them in physical memory.

• Segmentation divides memory into logical segments and stores them in physical memory.

• Both techniques allow for efficient use of memory and protection of memory from unauthorized access.

• Examples of operating systems that use paging and segmentation include Wind

Run time mapping between pages and frames is the process of mapping virtual memory pages to physical memory frames during program execution.

• During program execution, the operating system maps virtual memory pages to physical memory frames to ensure efficient memory management.

• This mapping is done dynamically and can change as the program runs.

• The mapping is maintained in a page table, which is used by the operating sys...read more

Critical section is a part of code that must not be executed by more than one thread at a time.

• It is used in multi-threaded programming to avoid race conditions.

• It is usually protected by locks or semaphores.

• Examples include updating shared variables or accessing shared resources.

• It is important for ensuring data consistency and preventing deadlocks.

Code for critical section in C/Java/C++

• Use mutex or semaphore to protect critical section

• In C/C++, use pthread_mutex_lock() and pthread_mutex_unlock()

• In Java, use synchronized keyword

• In C++, use std::mutex and std::lock_guard

• Ensure only one thread can access critical section at a time

Explanation of how sorting and searching complexities are derived.

• Sorting and searching algorithms have different complexities depending on the algorithm used.

• Sorting algorithms can be classified as O(n^2) or O(n log n) depending on the algorithm used.

• Searching algorithms can be classified as O(n) or O(log n) depending on the algorithm used.

• Complexities are derived by analyzing the number of operations required to comp...read more
