AutoIt Developer Hiring Guide

Hiring Guide for AutoIt Engineers

Ask the right questions to secure the right AutoIt talent among an increasingly shrinking pool of talent.

AutoIt is a freeware automation language for Microsoft Windows, originally developed in 1999. It uses a combination of simulated keystrokes, mouse movement and window/control manipulation to automate tasks not possible by Windows batch files. AutoIt was primarily designed to assist in automatically installing software that cannot be directly automated using standard Windows automation. The scripting language in AutoIt 1 and 2 was statement-driven and designed specifically for simulating user interaction. In its third iteration, it became more powerful and started supporting complex expressions, user functions, loops and everything else that veteran scripters or programmers would expect.

What will be the output of the following AutoIt code?

Local $i = 5
If $i > 3 Then
    ConsoleWrite('Greater than 3')
