I agree to that. The hard part of hiring is that it is a lot of customization for the specific environment of a company.
Hence my message. Talking about his past and future career, mine and the company's plan is the best thing for me to do, because I'm pretty that the other interviewers have not talked much about that, if at all.
And I'm confident that the hardcore technical interviews have been done. They don't need me to make it harder, except for a few select senior candidates. A for loop in a few languages written on the resume is enough (and it's fun for candidates who have "assembly") :D
