Will they be worth it?
Ever since someone pointed out to me (after I spent 3 weeks over xmas studying) that the answers can be downloaded I stopped giving my own money to Microsoft (via whatever test centre I was using at the time) for what I then considered to be a valueless piece of paper (the little enamel badge may have some recycle value). I still use the study materials on occasions as well as other online materials when working with new tech but I doubt I will give my(*) money to them again; the damage has been done. When interviewing we will give them a 1-on-1 coding session if they want to look something up via google they can (I do), I want to know how they think not what great memories they have for a piece of obscure/obsolete technology - anyone remember DataSets?
(*) if my employer wishes to waste their money then that is up to them.
