"I left my last job because everyone was incompetent but me. It went through two whole teams like this."
Wow - ego coming through! There are definitely incompetent people out there but to run into such a high proportion says that you either have truly terrible luck .... or that there's something wrong with your idea of competence.
"Oh, my weakness is I don't do automation."
This is only strange once you know that the position is for a QA Automation Engineer.
"I'm just looking for a job before my skills get too rusty."
On the one hand, this one is kind of sad. On the other hand, he's not doing anything to keep up or expand his skills, apparently, and that's a problem. I don't want to have to push for every new learning experience.
There are a lot of decent resumes out there. Phone screens really weed a whole lot out, though. Be careful what you say; the hiring manager is probably listening.
