Looking back, I can see how on one recent interview I didn’t get an obvious sub-question I should have, and how for the job I did land, the only reason I survived the whole interview process so well is that it was mostly done in the form of at-home questions, some of which I was battling the early symptoms of interview burnout on.
So what happened today was the first question (which I answered fairly well) pushed me over the edge and it was all downhill from there. Given that, it would have only gotten worse had I persevered. Ending it early was the best option.
I’m apparently in the minority in thinking this option is best. Most of the “experts” advise persevering. But really, perseverance is not always a virtue. No one thing is; life isn’t that simple. Too much of a good thing is a bad thing. Knowing how to recognize futility and give up is also a virtue (in moderation, of course, excessive lack of perseverance also a bad thing).
How it can be “good” to exhibit to a prospective employer that you’ll value some silly formality about “perseverance” even when it costs them money and your effort produces nothing but frustration escapes me. Me, I’d want an employee to quit a pointless task (and communicate this, of course) as soon as it became clear to him the task was probably pointless.
