Three parts: technical interview where a building schematic and questions were given, then talking through the answers to said questions, then generic interview questions about company / past experience, then case study interview where a brief were given to decide the feasibility of a project.

Phone screen asked questions like graduation date, working status, etc. Talked with 3 interviewer, got asked about some of the personal projects I did. Technical questions and second round of interview.

Standard interview questions. Technical question relating to improving energy efficiency of a building. Case study which was made difficult due to tight time constraints. 5 hour process, so it's hard work
