If it is consistant, and you know what it is before you go there, then it is fine. The "random" assignments could easily not be random. Being first or last in class could be a matter of 30-40 seniority spots. I just don't agree with something that can not be verified as random.

A HR person or recruiter could offer it to a candidate - we'll put you in the top 5 if you......... Oh, his dad is a Captain here, put him first (or last). She is the only female pilot, put her first. This guy is 60 years old, put him last. All of those things could easily happen when a nameless/faceless HR person or administrative assistant "randomly" picks the order on a computer.

Draw names out of a hat on the first day of class...at least that is more likely to be fair.
