This, so much this. Somehow, as if by magic, engineers always just know how good of an engineer somebody is after a thirty minute conversation. Just a conversation. You see this all the time in social settings.

While this is my favourite way to both give and get a technical interview, it does have a major flaw - measurability. In that there is none. The approach works when you're trying to hire one person every couple of months.

But I am fairly certain it breaks down when you have to decide between hundreds of applicants every week and you need to have a measurable and predictable process that goes beyond your engineers saying "I have a good feeling about them".
