The interviewer was quite disgruntled at my experience, in which case don't take someone through to prescreen (it wastes everyone's time)
It wasn't what a usual prescreen interview entails it was more like a 1st stage interview
The role sounded different to the JD and I subsequently found out they'd tired to hire a few times for this role (very telling)
It took nearly 2 weeks to contact me after a prescreen (this isn't normal)
