- Who is this Cloud Architect interview plan for?
- It is written for the interviewer, not the candidate: the hiring manager, engineer or panel member running the Cloud Solution Architecture Q&A round for a Cloud Architect role. It gives you a 60 min script to follow in the conversation — 9 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 Cloud Solution Architecture Q&A round assess?
- This round is focused on: Cloud Solutions, Service Knowledge, Networking, Storage Solutions, Serverless Computing. It works through Cloud Solutions and Service Knowledge, Networking and Storage Solutions and Serverless Computing and Project Leadership, scoring against 61 observable signals, with follow-up prompts on all 9 questions for going deeper where an answer is thin.
- How is the 60 min split up?
- The plan times 55 of the 60 min: 5 min opening, 45 min on 9 questions and 5 min closing. The questions take in Cloud Solutions and Service Knowledge (15 min), Networking and Storage Solutions (15 min) and Serverless Computing and Project Leadership (15 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.
