Postdoc interview with many inquiries I was invited for a postdoc interview. It was 1h 30min long with 2 professors (via Skype). After the interview, they asked me to present at their lab meeting in the next 2 weeks (optional, about my PhD studies, also via Skype). In addition, they also asked me to send my PhD thesis (optional, before the meeting). So is it normal for PI to request so many things like this for non-advertised postdoc position? Should I agree to do all of the inquiries? They ask for my thesis before the meeting - it looks like a second PhD defense.

So is it a good place to work? Do you guys think this PI is too hard?
The PI isn't asking for anything unreasonable.  In fact, I really like the idea of participating in the lab meeting via Skype.  This way the mentor can see how you interact with the whole lab without adding major inconvenience or expense.

As to "Should I agree...?"  -- if you'd like the job, you should probably do it.
