How to prepare for your Civil Engineer interview
Revise core subjects: strength of materials, structural analysis, RCC/steel design and fluid mechanics.
Know practical construction: concrete grades, mix design, water-cement ratio, curing and common field tests (slump, cube).
Be ready on estimation and site work: bar bending schedule, quantity estimation, scheduling and quality control.
Brush up on relevant codes (IS 456 for concrete) and standard values you'd be expected to recall.
Prepare site-scenario answers and any project/internship experience — interviewers probe real on-site judgement.
