Walked around the SIG building for 20 minutes ending at interview room, not sure what was achieved by this as undergoing relocation this month. Handed a question/exam form to fill out which would be used for questioning and I had 20 mins to complete. This was not used. I understood interview would be conducted by two developer team leads and hiring manager, no hiring manager. I was asked "Tell me about yourself" then requested to draw a diagram on a white board of a system supported. Questioned on this for about 25 minutes. Asked how I heard about the job. Asked why I wanted the job.
