Frequently asked questions

Does Llanwern steelworks ask system design questions for software engineers?

For most mid and senior software engineer roles, Llanwern steelworks includes at least one system design round alongside coding and behavioural interviews. Junior and new-grad loops lean more heavily on data structures, algorithms, and a behavioural round.

How should I prepare for the Llanwern steelworks software engineer behavioural round?

Prepare 5–7 STAR stories covering ownership, conflict, failure, and cross-team work, each with a clear personal contribution and a measurable outcome. Practising them on camera with a timer is the fastest way to tighten delivery.
