thanks,
I don't want to put him on the spot by ringing and saying, Hi its me, any date for an interview etc. If I disturb him when he's busy, or catch him off guard, it might just annoy him. And yes he is male so don't want to challenge him into doing 2 things at once either ;-)
So, I think I'll go with one more mail and see what happens. Make an enthusiastic, I'm up for an interview one...I am finding it hard with the job hunt until this is out of the way.
thanks again !!
