Cast & Crew Interview Questions and Answers

Technical Lead interview questions on mutex, thread communication, CompletableFuture, and deadlock

• Mutex is a synchronization mechanism to prevent multiple threads from accessing shared resources simultaneously

• Thread communication can be achieved through shared memory, message passing, or synchronization primitives like semaphores

• CompletableFuture is a Java class that represents a future result of an asynchronous computation and provides methods to chain and combine them

• Deadlo...read more

I have worked with several design patterns including Singleton, Factory, Observer, and Decorator.

• Implemented Singleton pattern to ensure only one instance of a class is created.

• Used Factory pattern to create objects without exposing the instantiation logic to the client.

• Implemented Observer pattern to notify dependent objects of any state changes.

• Used Decorator pattern to add functionality to an object dynamically without changing its structure.

Neural network is a type of machine learning algorithm inspired by the human brain, consisting of interconnected nodes that process information.

• Neural network is composed of layers of nodes, each connected to nodes in the next layer.

• Nodes in a neural network perform mathematical operations on input data and pass the result to the next layer.

• Neural networks are trained using labeled data to adjust the weights of connections between nodes.

• Common types of neural networks include...read more
