My interactions with NCCLF staff was for the most part courteous, timely and professional.
My compliant -- and I think it's a pretty major issue -- is that they took the initative of calling what-was-then my current employer for a reference. I hadn't yet provided formal professional references, nor had they asked for any at that stage of the interview process -- and if I were to have provided refererences it would most definitely NOT been for my current work (and I think that's standard practice during a job search, isn't it?). NCCLF didn't even bother to tell me they were calling my current employer; I found out about it because my boss at that time told me they called. Needless to say, that was an awkward conversation.
