I applied via Approached by Company and was interviewed in Dec 2022. There were 3 interview rounds.
Hackerrank coding test related to Java 8, Spring Boot and some other JPA stuff. The recruiter just told me that it was an online coding challenge so I did not know what to expect or what to prepare. I just thought it would be some DSA or puzzle challenge round. I think it was 30 questions in 30 minutes of something like that.

HTTP request passes through multiple network layers before reaching the server.
HTTP request is first sent from client to local network router.
Router forwards request to Internet Service Provider's network.
Request then passes through multiple routers and switches in the internet backbone.
Finally, request reaches the server hosting the requested website or service.
Each network layer adds its own headers and metadata to t
HTTP is stateless because it does not retain information about previous requests.
HTTP treats each request as an independent transaction without any knowledge of previous requests.
This design simplifies implementation and improves scalability.
State information can be managed using cookies or session tokens.
Example: When a user logs into a website, the server may create a session token to track the user's activity.

Promises, async/await, and callbacks are all ways to handle asynchronous operations in Node.js.
Callbacks are functions passed as arguments to another function and called when the operation is complete.
Promises represent a value that may not be available yet, but will be resolved at some point in the future.
Async/await is a syntax for writing asynchronous code that looks like synchronous code.
Callbacks are the oldest an...
Promises are used in Node to handle asynchronous operations and avoid callback hell.
Promises simplify error handling and make code more readable.
Promises allow for chaining multiple asynchronous operations.
Promises can be used with async/await to write synchronous-looking code.
Example: fetching data from an API using axios library with promises.
Example: reading a file with promises in Node's fs module.
