Who is this Infrastructure Engineer interview plan for?

It is written for the interviewer, not the candidate: the hiring manager, engineer or panel member running the Technical Interview round for a Infrastructure Engineer role. It gives you a 60 min script to follow in the conversation — 10 questions with what each one is for and the signals to score against — so you are not writing the round from scratch the night before.

What does the Technical Interview round assess?

This round is focused on: Infrastructure Design, Technical Expertise, Networking, Virtualization, Cloud Services. It works through Introduction, Infrastructure Design, Technical Expertise, Networking and Virtualization, Cloud Services and Closing, scoring against 70 observable signals, with follow-up prompts on all 10 questions for going deeper where an answer is thin.

How is the 60 min split up?

Introduction (5 min), Infrastructure Design (10 min), Technical Expertise (10 min), Networking and Virtualization (10 min), Cloud Services (10 min), Closing (5 min). The timings are there so the round stays on schedule and every candidate gets the same shape of interview — which is what makes two candidates comparable afterwards.

What other rounds should I run for a Infrastructure Engineer?

A single round does not cover a whole role. The other rounds in this library for a Infrastructure Engineer are Behavioral Interview, Infrastructure Planning Q&A, Problem-solving Test, System Design Interview and Technical Presentation. Each is a separate plan you can use as it is.
