Called me after i'd left work yesterday and left no message. Called again a few minutes ago asking for someone that doesn't even work in my area - apparently they're stupid enough to pick the first person they saw on our online staff list with "Director" in the title, then decided to randomly pick my number to try and reach them. Neither myself or the other person are a CTO.
3 more calls identical to my last post - same number, same guy with a heavy Indian accent (obviously in a call center) calling the wrong number for the wrong guy.
