Acronyms you should know when going to a job interview.

In past job interviews, way before getting a dev job I have had a few embarrassing experiences not knowing what a specific acronym from the world of web development means and what it does.

We often find ourselves using some technology for a long time and just skipping or forgetting the basic information of that technology even after extensive use. Being able to name an acronym and explain it in a few sentences can tip the scale in your favor (if the other parts of the interview were not a disaster).

I will skip the basic acronyms that we all know (WWW, HTML, CSS, HTTP) and write a list of acronyms that as a web developer you should know when going to a job interview.

The “should” in the last sentence is of course very relative and/or different from person to person and depends on the type of the job that you are after and the knowledge that you have (knowing an acronym does not help much if you don't know anything else about the thing).

So, this list is based on my experience with attending a number of job interviews for a web developer position (front-end & back-end).

(sorted A-Z)

API - application programming interface

A set of subroutine definitions, protocols, and tools for building application software.

AJAX - Asynchronous JavaScript And XML

a set of Web development techniques using many Web technologies on the client side to create asynchronous Web applications. With Ajax, Web applications can send and retrieve data from a server asynchronously (in the background) without interfering with the display and behavior of the existing page.  In practice, modern implementations commonly utilize JSON instead of XML due to the advantages of JSON being native to JavaScript.

CDN - Content Delivery Network

A network of distributed servers that store duplicate copies of our web content.
CDNs allow us to deliver content to each user from a server that is closer to their location or less overloaded. This way we can achieve better performance and reduce server downtime.

CORS - Cross-Origin Resource Sharing

A mechanism that allows restricted resources (e.g. fonts) on a web page to be requested from another domain outside the domain from which the first resource was served.
 It allows for more freedom and functionality than purely same-origin requests, but is more secure than simply allowing all cross-origin requests.

CRUD - Create, Read, Update, Delete

A term used in database management, it contains the four basic functions of a persistent database.
In SQL, the four related commands are: INSERT (for Create), SELECT (for Read), UPDATE (for Update), and DELETE (for Delete).
CRUD functions describe the typical data life cycle on dynamic websites.

IIFE -  Immediately-Invoked Function Expression

A JavaScript programming language idiom which produces a lexical scope using JavaScript's function scoping. Immediately-invoked function expressions can be used to avoid variable hoisting from within blocks, protect against polluting the global environment and simultaneously allow public access to methods while retaining privacy for variables defined within the function. This concept has been referred to as a self-executing anonymous function, but Ben Alman introduced the term IIFE as a more semantically accurate term for the idiom, shortly after its discussion arose on comp.lang.javascript.

JSON - Javascript Object Notation

An open-standard file format that uses human-readable text to transmit data objects consisting of attribute–value pairs and array data types (or any other serializable value).JSON is a language-independent data format. It was derived from JavaScript, but as of 2017 many programming languages include code to generate and parse JSON-format data. The official Internet media type for JSON is application/json. JSON filenames use the extension .json.

MVC - Model View Controller

Commonly used for developing software that divides an application into three interconnected parts. This is done to separate internal representations of information from the ways information is presented to and accepted from the user. The MVC design pattern decouples these major components allowing for efficient code reuse and parallel development.

ORM - Object-Relational Mapping

A technique that lets you query and manipulate data from a database using an object-oriented paradigm. When talking about ORM, most people are referring to a library that implements the Object-Relational Mapping technique, hence the phrase "an ORM".
An ORM library is a completely ordinary library written in your language of choice that encapsulates the code needed to manipulate the data. In that way you interact directly with an object in the same language you're using.

UX - User Experience

User Experience refers to a person's emotions and attitudes about using a particular product, system or service. It includes the practical, experiential, affective, meaningful and valuable aspects of human–computer interactionand product ownership. Additionally, it includes a person’s perceptions of system aspects such as utility, ease of use and efficiency. User experience may be considered subjective in nature to the degree that it is about individual perception and thought with respect to the system. User experience is dynamic as it is constantly modified over time due to changing usage circumstances and changes to individual systems as well as the wider usage context in which they can be found. In the end user experience is about how the user interacts with and experiences the product.

Thirty (30) acronyms conclude this list. It could have been longer. Maybe it should have been shorter. That is completely up to each individuals wishes and goals.

I was aiming for a full-stack web developer job, using PHP and its frameworks, Javascript and its frameworks and so on...

So if your goals are in that area or you just want to extend your knowledge a bit, this information here should be helpful.

And because I think some additional knowledge is always good no matter what – here is a quick list of some more interesting acronyms.


  • SCM – Source Control Managment
  • FTU – First Time Use
  • AMP - Accelerated Mobile Pages
  • SHA - Secure Hash Algorithm
  • DDD - Domain-Driven Design
  • JSX – Javascript XML
  • B2B - Business to Business
  • B2C - Business to Customer
  • B2G - Bussines to Goverment
  • DBMS - Database Management System
  • DNS - Domain Name System

Do you think something is missing on this list? Do you think something should not be on this list? Let me know.

We definitely take for granted how non-obvious most of this list is. Acronyms are sometimes silly but you kind of have to know it all to play the game.
