When you’re interviewing for a dream job, remember this: everyone interviewing you has broken a live build or made some similar epic screwup in the past. Some of the people interviewing you are worried about their next performance review.
They’re not a different species because they work at some company you’ve put on a pedestal. Treat them as respected colleagues, not heroes. If you don’t see yourself as being cut from the same cloth, why should they?
They’re on the same path as you, just a few years down the road.
