Many companies I've dealt with seem to forget that the person they're interviewing probably isn't interviewing with just one company.

The last place I worked for (government) was maddening in this respect. We'd find a great candidate and HR would delay or otherwise jerk them around, and then have the gall to be shocked when the person accepted another offer.

In my recent job search the company I joined had a written offer to me within a day or two. Others contacted me weeks later with offers, even after I told them I was considering multiple offers at the time.

I don't think most candidates will tell you that, but that's likely the case. You snooze, you lose. There aren't many reasons you can't make an offer within a week after an interview.
