208 architecte d applications interview questions shared by candidates

The first question was one I asked of *him*. I asked if this hiring process was the same for recent grads as it was for a 30+ year experienced IT manager. He said yes. He started asking questions like "what do you want to do with your life", and "tell me about yourself", "What would you do if the customer wanted an S3 object with specialized billing", and "Tell me about your failures". All the amateurish BS you'd expect.
