A long while ago I went to a job interview with a thoroughly weird company in London who claimed to be expert Unix consultants. Anyway these people were complete nutters and not surprisingly the company doesn't seem to be there any more, but at the interview they asked me the following question:
What is the first call you make to start a new process?
So I answered that the first call is
fork. The two people interviewing me said (very insistently, as if I'd missed something utterly obvious)
What call do you do before you do the fork?
Now, I have no idea about this question, and I have to say these people convinced me they were unmitigated idiots for reasons completely unrelated to this question, but for some reason this question still bugs me even now. Is there some call which is made before a fork? Is there some subtlety I missed out on?
