I cannot answer any question in conversation with a stranger unless the answer is something I happen to know off the top of my head, or the question is about what I can see or feel or remember in the moment. It's related to a general sort of cognitive disability I have that shows up in several other ways.
For example, if I'm driving and you engage me in conversation, we will get lost. Every time.
If I'm playing a multiplayer game with voice chat, and people are talking to me, I will lose.
There are just certain cognitive activities that I cannot combine successfully. The presence of a stranger in conversation forcibly occupies all of my attention. I am unable to think about anything other than interpreting the stranger's utterances and preparing my own. If I try to, for example, answer questions about FizzBuzz that require me to actually think about how things work, my mind goes completely blank.
"I'm trying to think, but nothing happens."
I presume that in each case where I received an offer, it was because the team had information from other channels that made me attractive. I know it for a fact in a couple of cases.
So in recent years I've mostly relied on those other channels, and just skipped the so-called technical interview. All it's going to tell you about me is that I can't do what you want me to in a technical interview.
