It's practice for your interview skills. If you're on a job interview, and you say 'ls -lha' when the interviewer is expecting 'ls -lah', chances are good you will be marked wrong, and may be passed over in favor of a candidate with "stronger command line skills".

But neither of those options is more or less correct than the other; there is no way to know which a strict (but apparently unqualified!) interviewer is going to prefer.
