This. I once had a code review with a new hire who couldn't understand a for loop in C#. Something almost as simple as the snippet below. Their resume showed a B.S. in CompSci from a CalState school. But they professed "I never understood loops".

  for(int i = 0; i < 100; i++)
  {
    newList[i] = sourceArray[i];
  }

I've also been in working environments where management has insisted that the code reviews be moderated by someone who was a mechanical engineer with no code/software training, background, or experience. I didn't particularly enjoy those....
