I once told a hiring manager I was “proficient in SQL.”
In reality, I had watched half a YouTube tutorial on 2x speed.

In the interview, she said:
“What’s the difference between INNER JOIN and LEFT JOIN?”
I said:
“It depends on your mindset.”

I blacked out.
She smiled. I think it was pity.

Lesson?
Lie if you must. But memorize the script.
And never lie about tech. They will test you immediately.
