I was interview by my then manager and the HR manager at the time, they took me to the boardroom and mainly talked about my past experience and if I was good at working and communicating with other.

Interviewers were polite and respectful. Asked very specific questions and your answers determine if you are offered the position regardless of your years of experience. If you have this stuff memorized it's fine but typically in your day to day tasks as an Electrical Designer, these specific things won't come up.
