• Knowing the fundamental of js. This is a must, since this is js. lol
• Learn how to design and implement rest api
• Learn the basic concepts of nodejs (event loop, single thread), it's advantage and disadvantages.
• Know atleast 1 framework, preferably expressjs. (This is not necessarily to learn, as long as you have a solid understanding of how nodejs works)
• Learn any of two db's (mongo or sql) or maybe both.

And last but not the least, before the interview, get your hands dirty (practice practice practice!!!), building some stuff that is built on nodejs, maybe you can showcase it to your interviewer.

Goodluck :D

Hi I graduated as an electronics engineer sand now I work as Web Developer. I think the best way to learn is through working on simple projects.

I also have my own YouTube channel where I create simple projects to learn more into programming. Check it out here - youtube.com/channel/UCtHEWTpi4_DCKzhOgeYUwug

I have also shared my story here - hashnode.com/post/my-journey-from-electroni..

Thank you :) Disha

This is just my two-cents.

It is all about you. If you don't know the answer to something, just say that you are unsure. If you have a small idea on how it works, let the interviewers know what you think the answer might be.

Sometimes, I feel that it is the human touch that matters. The fact that you are able to say that you do not know and let everyone move on from there. Heck, the interviewer might even tell you the answer and you guys can continue to have a discussion.

Again, this is my opinion and it may be against the "best practices" of interviews out there.

Hard to say without knowing your skill level.

• Know your JS fundamentals including some quirks and tricks. "this" , object-deconstruction currying ect.
• Know about JS's single threaded nature and the event-loop
• Know the similarities and differences between the browser and a node environment
• Know JSON and how to manipulate it
• Know SQL and Mongo to a good degree
• Know the Http protocol including http2 and websockets
• Know how to implement a static file server
• Know how to design and implement a Rest API
• Know at least the core concept of GraphQL

Some useful libraries might be

• lodash
• bluebird
• log4js/Morgan
• express
• socket.io
• sequelize

• Read about common interview questions about personality and such, and of a few examples to support each answer.
• Practice some coding puzzles on one of the various internet sites like Hackerrank.
• Read about some basic concepts that you may be using and familiar with, but not able to explain. Like prototype inheritance, or MVC.
