ServiceNow
Also written as ITSM, IT Service Management, ITIL
A cloud platform companies use to run IT support and internal workflows such as tickets, change requests, asset tracking and HR requests. ServiceNow developers customise it with JavaScript and build workflows on top of it. ITIL is the process framework it usually implements.
Think of it like
The company's service desk, rebuilt as an app every department can plug its own request forms into.

Senior sounds like
Has built custom apps or integrations on it, not only closed tickets inside it.
Ask them

Sounds like real experience
Describes a workflow, integration or custom app they built, and mentions platform-specific pieces such as scripts or Flow Designer.
Probe further if
Their experience is raising and resolving tickets as an IT support agent, which is using the product rather than developing on it.
