Not defending it, just mentioning why it might be that way at large corporations. Also note that it'll take the interviewer extra time to do their writeup afterwards, so it does amount to extra work on their part. At smaller companies they'll probably have less bureaucracy, so they can make hiring decisions quicker with less paperwork. Also team members will care a great deal more, since they'll be personally working with the candidate.
