How to prepare for your Structural Engineer interview
Revise limit state design and the relevant IS codes — IS 456, IS 800, IS 875, IS 1893 — with their key clauses.
Be fluent in your analysis software (STAAD.Pro or ETABS): modelling, load combinations and result interpretation.
Understand load paths and foundation selection; carry one structure you designed and can defend.
Practise quick hand calculations for beam/slab/column sizing — interviewers test design intuition.
Know seismic and wind load basics per IS 1893 and IS 875, and how they drive lateral system choice.
