While I manage with most of these interviews, I feel that there is a room for improvement...
How were some of the technical interview that you think were planned well?
>Can the candidate make sound search queries?
>Can the candidate setup an environment?
>Can the candidate into version control?
>Can the candidate into debugging some piece of code?
Pretty much sums it up
EDIT : Also, punctuality is key, lateness is not acceptable. All Stakeholders must be present to start the meeting, we can't afford to wait.
