The interview is an opportunity to clarify and explore the evidence in your application. The strongest preparation is to know your own examples well enough to explain the decisions and responsibility behind them.
Use your application as your starting point
Review every major example you submitted. Be ready to expand on the technical context, your personal contribution, constraints, alternatives, risk and outcomes.
Prepare a concise presentation
Choose one or two pieces of work that show the depth of your technical reasoning and approach to engineering problems. Keep the project background proportionate and ensure your own role is obvious.
Expect questions beyond the presentation
Prepare across knowledge, engineering problem solving, responsibility and leadership, communication, and professional commitment. A narrow technical presentation does not remove the need to discuss the rest of your work.
Avoid two common traps
Do not turn every answer into a team story. And do not claim certainty where the work involved limits, escalation or a need to seek specialist input. Knowing the limits of your responsibility is part of professional judgement.
