Every recruiter has a horror story about a candidate who failed to progress in through the selection process because the candidate turned up late, went to the wrong location or wore inappropriate attire.  Most of the time, recruiters are quick to blame their candidates when mistakes like this arise.  However, a good recruiter recognises that most of these problems can be avoided if the practical preparation is good and thorough enough.  Don’t be too afraid of patronising candidates by giving them advice that you might consider to be common sense – if there’s one thing we know about common sense, it’s that it’s not that common after all!  Basic elements like location, travel, timing and dress code are the kind of considerations which won’t ensure that they get the job if they get them right but will almost certainly ensure that they don’t progress if they get them wrong.
