When asked how I'd do some contrived text processing task, I replied "I'd look at the wiki page for grep and futz until something worked." (Today I'd probably start with 'tldr' command.)

Like I've done my entire career. Most of our job is mygyvering crap. Esp for scrubbing data.

"Well, ya, that'd work. And probably what I'd do too."

Next interviewer really grilled me about parsing and spam detection. For a UI job. When I explained some of the grammars I did write, for a hobby project, this "bar raiser" dismissed the effort by saying "well, that's nothing, lex/yacc did all the work." (To my overlasting shame, I sarcastically replied "Ya, and my compiler writes all my code too.")

Next interviewer, the engineering manager, grilled me, repeatedly, about how I'd choose between two options, using his current dilemma as the example. (Because apparently I was interviewing to replace him.) I related my prior experiences, eg satisficing. Not good enough. Try both options? Nope. Take a vote? Naw, that'd be too adversarial. Flip a coin? Oh, please, that's not rational.

I didn't get the job.
