Technical Interview Questions & Answers

Q1: What is the difference between a synchronous (before/after) Business Rule and an Async Business Rule in ServiceNow?

Before/After Business Rules run synchronously within the same user transaction thread—meaning the user's screen waits until the script finishes executing, which can degrade user performance if external API calls or heavy loops are performed. Async Business Rules run in the background via the ServiceNow scheduler queue after the database change has been committed, freeing up the user interface immediately for better performance.
