The Director of IT and the CTO conduct the interview. You are seated in a small room and the Director of IT politely and professionally begins the interview and shortly thereafter the CTO enters. There are few to zero quantitative type questions in short its a qualitative interview process.You are invited to go a board and write out answers to a question. However they force you in their direction and if necessary guiding you back to where or what they wish to focus on. And although you are applying for a software engineering job they choose to focus intensely on the first tier or database design. The reason no doubt is their expertise is not in the front end this any skilled developer will determine after a few questions about the technology they currently use. After less than 50 minutes the CTO may just end the process by saying 'I have to catch a plane' -it happened to me-in short you may have just wasted your time. But then to be fair that can be the response if for some reason you missed something or its determined you are getting an offer and they figure why contiune. And lets be fair thats what interviews are for to determine if a candidate is a good fit. No doubt if you are a good fit you may be treated a lot differently. To sum it up:don't take it personal.
