All night we hack,
And sleep we lack.
We eat junk food,
The code is crude.
Nevertheless,
Friends are impressed,
When in the morning,
Our post on HN* is roaring!
Could you point what was his expectation culture wise and the company's situation? What exactly he didn't like except the wrong questions?
I wish I left some interviews early :)
In the end it's important to leave on a good impression for future connections but probably those people (in your friends company) were arrogant immature kids in the first place and they don't care about good future connections anyways. In this case don't waste your time.
Same for the interviewers - please let the people know early on and save their time instead of being "polite" and dragging them into meetings multiple people (usually with the same dumb questions) or even stretching interview process into multiple days!
