Learnability

Do you remember the Pythagorean theorem in the context of right-angled triangles?

An interviewer asked a candidate to state the theorem in a job interview. The candidate answered it perfectly.

Now, the interviewer asked him to prove it. The candidate faltered because he didn't remember the proof.

So the interviewer said, "If I give you ten minutes to prepare, could you show me the proof?" The candidate said he could.

So he learned it and presented it.

He was hired.

According to a recent study, the most essential skill for job success is not intelligence, perseverance, or communication.

It's learnability.
