I received a call from a recruiter and was asked basic questions about my experience, what type of work I was interested in, and salary requirements. After that, I attended an interview that felt like speed dating.

There were several others who were interviewing for different positions. We were all led into a room, and each one of us sat at a separate table. I was interviewed by 3 team leads from different sectors (software developer, operation research, and process engineer). Each person interviewed me for about 30 minutes and generally asked me questions based on my resume. After the interview session, HR advised that they would contact each of us to provide feedback. That didn't happen, and I didn't even bother following up with them.

What is a design pattern? Have you used them?
