Udemy – Electrical Engineering Interview Guide: Plant & EPC Design

Are you preparing for an Electrical Design Engineer interview at top EPC companies, oil & gas projects, or global engineering consultancies? Knowing formulas is one thing, but delivering precise, calculation-backed answers under interview pressure is what gets you hired. This Electrical Engineering Interview Guide for Plant & EPC Design bridges that exact gap. Based on real hiring panels from leading EPC firms, this course delivers 150+ high-frequency technical interview questions and answers with direct engineering explanations. Instead of generic theoretical derivations, every answer is structured around real project deliverables, vendor documentation, and international codes (IEEE, IEC, IS).

What You Will Master in This Course:

• Core Equipment Sizing & Design:Transformer sizing criteria (%Z trade-off), HV/LV cable sizing & voltage drop calculations, motor starting impact (DOL vs. Star-Delta vs. Soft Starter vs. VFD), and switchgear breaking/making capacities.
• Substation & Protection Systems:Current & Potential Transformer (CT/PT) knee-point voltage sizing, ANSI protection relay codes (50/51, 87, 64R), and substation grid earthing design per IEEE 80.
• EPC & Consultancy Engineering Workflows:Design Basis Report (DBR) preparation, Technical Bid Evaluation (TBE), Vendor GA drawing review, Single Line Diagram (SLD) development, and Inter-Disciplinary Coordination (IDC).
