What PowerShell questions are asked in an interview?

Expect basics (cmdlets, the pipeline, execution policy), scripting (functions, scopes, modules), error handling with try/catch, remoting with Invoke-Command, and Windows PowerShell 5.1 vs PowerShell 7. Senior rounds add scenario questions where you write a short script.

Should I learn PowerShell 7 or Windows PowerShell 5.1 for interviews?

Learn PowerShell 7, and know where 5.1 differs, since many servers still run 5.1 scripts. Microsoft's differences between 5.1 and 7 page lists every breaking change.

Which execution policy is the default on Windows?

If no policy is set, Windows clients use Restricted and Windows Server uses RemoteSigned. The about_Execution_Policies documentation explains every scope.

How do I prepare for a PowerShell scripting interview?

Write small scripts for real tasks: parse a CSV, filter a log, call a REST API, and handle errors. Be ready to explain objects vs text and why you'd pick a function, module or job.

Is PowerShell still worth learning in 2026?

Yes. It runs Windows administration, Microsoft 365 and Azure automation, and PowerShell 7 works on macOS and Linux too, so the skill carries across platforms.

50 PowerShell Interview Questions and Answers (2026)

Most PowerShell interview questions come back to one idea: PowerShell passes .NET objects, not text. If you can show that in two lines, you’ve answered half the screening round already:

$file = Get-Item .\orders.csv
$file.GetType().Name
$file.Length

Output:

FileInfo
136

Get-Item returned a FileInfo object, so the file size is a real number you can sort, compare and add up. A text-based shell would hand you a line to parse instead.

Below are 50 questions I’d ask (and have been asked), grouped from beginner to scenario rounds. Each code answer ran in PowerShell 7.6 and Windows PowerShell 5.1, and the answers point out where the two shells disagree.
