The interview process was a three step process, the initial meeting, the detailed interview, and the final management meeting.
For the first part, I met with two peers of the office and presented my portfolio, answering a couple questions about my interests, and abilities. It took place at the office, and was very informal, like having coffee with a friend you hadn't seen in a while.
The second part was presenting my portfolio again to a senior manager along with the same peers, this time answering some more specific questions about the portfolio content, and a couple skill testing questions about CAD usage. I was also asked about my interests and hobbies.
The third part was meeting with the company owner, and having a short discussion about who my teachers where, what really interested me about the field, and what kind of hobbies I had.
