Hewlett Packard Enterprise Senior Software Developer Interview Questions, Process, and Tips

HTTP/1.1 is the older version with persistent connections, HTTP/2.0 introduces multiplexing and server push, and HTTP/3.0 uses QUIC protocol for faster performance.

• HTTP/1.1 uses persistent connections for each request/response, leading to potential performance issues.

• HTTP/2.0 introduces multiplexing, allowing multiple requests/responses to be sent over a single connection simultaneously.

• HTTP/2.0 also supports server pu...read more

Print all possible subsets from a given slice of integers

• Use recursion to generate all possible subsets

• For each element in the slice, include or exclude it in the subset

• Keep track of the current subset being generated

Context package in Go language provides a way to pass around deadlines, cancellation signals, and other request-scoped values.

• Context package is used to manage deadlines, cancellation signals, and request-scoped values in Go programs.

• It allows passing data between function calls without having to pass them explicitly as arguments.

• Context package is commonly used in web servers to manage request-specific data and timeou...read more

REST API is a standard protocol for web services using HTTP, while gRPC is a high-performance, open-source RPC framework.

• REST API uses HTTP for communication, making it easy to implement and widely supported.

• gRPC is a modern, high-performance RPC framework that uses HTTP/2 for transport and Protocol Buffers for serialization.

• gRPC is more efficient in terms of performance and supports features like bidirectional streami...read more

Use copy() function to create a new slice and reflect changes in original slice to the new slice.

• Use the copy() function to create a new slice with the same length as the original slice.

• Make changes to the original slice.

• The changes made to the original slice will automatically reflect in the new slice as well.

GoLang is best for its simplicity, efficiency, concurrency support, and strong community backing.

• Efficient performance due to compiled nature and garbage collection

• Concurrency support with goroutines and channels

• Strong standard library with built-in support for networking, encoding, and more

• Simple and clean syntax that promotes readability and maintainability

• Growing community and ecosystem with popular frameworks like

Kubernetes is an open-source container orchestration platform for automating deployment, scaling, and management of containerized applications.

• Kubernetes follows a master-slave architecture with a master node controlling multiple worker nodes.

• Master node components include API server, scheduler, controller manager, and etcd.

• Worker node components include kubelet, kube-proxy, and container runtime (e.g. Docker).

• Kubernet...read more
