General CV overview, walked through high-level examples of change and project/programme delivery. Invited to 2nd round interview but declined to attend based on lack of transparency and poor candidate experience.

On interviewer spoke broken english and was very hard to understand, asked textbook and theory questions and not in a very clear process, seemed like he Googled and wrote down a bunch of questions from a search to ask prior to the interview, saw notes and theory written on a legal pad. Asking questions on free body diagrams, mechanics and thermodynamics, like write and explain Gibbs free energy equation and explain the three laws of thermodynamics. Did not ask too much that would be used daily as the job was described, the theory can be referenced in a book or Googled when needed, people do it all the time and little is used daily unless you work in a research. No applicable skills and appears this person was a recent fresher with not too much practical experience in the field.
