- 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 Presentation round for a Infrastructure Engineer role. It gives you a 60 min script to follow in the conversation — 2 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 Presentation round assess?
- This round is focused on: Presentation, Communication, Technical Documentation, Stakeholder Engagement, Reporting. It works through Technical Challenge, scoring against 13 observable signals, with follow-up prompts on both questions for going deeper where an answer is thin.
- How is the 60 min split up?
- 5 min opening, 50 min on 2 questions and 5 min closing. The questions take in Technical Challenge (50 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.
