Forgot to post about the interview.
It went very well yesterday though the manager and sub-manager aren't the type of people I'd normally have much to do with at all.
They were nice, but not my type, if that makes sense. Before I even reached my flat that evening, I got a call from them inviting me for a trial today. So I've just returned after an hour of selling and am waiting to see if I get a call again today or tomorrow. If they do call, it means I can start.
No idea how it went. I thought it was good. I am not the sort of person who jumps on people and stays with them all the time. So I just greeted them and spoke to them when they were looking at certain products, told them about them, demonstrated some things and tried to find out what sort of things they generally like. So that's the sort of salesperson I'd like around me, but I have no idea if that was all right with my colleagues. We'll find out.
