Cognizant Software Developer Interview Questions, Process, and Tips

In the first year, the goal is to integrate into the team, contribute to projects, and enhance skills through collaboration.

• Understand the codebase and architecture by reviewing documentation and existing code.

• Contribute to at least two major projects, such as developing a new feature or optimizing an existing one.

• Participate in code reviews to learn best practices and improve code quality.

• Engage in regular team meetin...read more

final, finally, and finalize serve different purposes in Java: variable declaration, exception handling, and garbage collection, respectively.

• final: Used to declare constants. Example: final int MAX_VALUE = 100;

• finally: Block that executes after try-catch, regardless of exceptions. Example: try { ... } catch { ... } finally { cleanup(); }

• finalize: Method called by the garbage collector before an object is removed. Exam

In JavaScript, '==' checks for value equality, while '===' checks for both value and type equality.

• '==' performs type coercion, converting operands to the same type before comparison.

• '===' does not perform type coercion; both value and type must match.

• Example of '==': 5 == '5' returns true because '5' is coerced to a number.

• Example of '===': 5 === '5' returns false because the types (number vs string) are different.

CNN stands for Convolutional Neural Network, a type of deep learning algorithm used for image recognition.

• CNN is a type of deep learning algorithm commonly used in image recognition tasks.

• It consists of multiple layers such as convolutional, pooling, and fully connected layers.

• Convolutional layers apply filters to input images to extract features.

• Pooling layers reduce the spatial dimensions of the convolved feature.

• Ful...read more

LLMs and GENAI are machine learning models used in natural language processing. Vectors are mathematical representations of words or phrases.

• LLMs (Large Language Models) are advanced machine learning models used in natural language processing tasks such as text generation, translation, and sentiment analysis.

• GENAI (Generative Adversarial Network for Artificial Intelligence) is a type of machine learning model that uses...read more

RNN stands for Recurrent Neural Network, used for sequential data. LSTM is a type of RNN with long-term memory capabilities.

• RNN is a type of neural network designed to handle sequential data by maintaining a hidden state that captures information about previous inputs.

• LSTM (Long Short-Term Memory) is a type of RNN that addresses the vanishing gradient problem by introducing gates to control the flow of information.

• Impl...read more
