Do

Show a clear, repeatable troubleshooting method — do not jump to a guess.
Explain technical steps in plain language, as if to a non-technical user.
Prepare examples of handling a difficult user calmly.
Know Active Directory basics (accounts, groups, password resets) cold.

Avoid

Guessing at fixes instead of isolating the problem methodically.
Weak communication — being unable to explain a fix simply.
Ignoring the ticketing/SLA and escalation side of the job.
No customer-service example for the behavioural questions.
