The Role of Tech Interviews
Tech interviews are highly sensitive as they are the determining step to assess the suitability and employability of a candidate for a position. Therefore, I don't advise collecting a set of questions with which you are not familiar. If you do, how can you fully appreciate the candidates' answers?
Who Should Conduct Tech Interviews?
On that note, tech interviews should be left to the tech team rather than HR to handle.
Considerations for Listing Tech Interview Questions
If you attempt to list them out, keep in mind that IT is a very vast subject, ranging from hardware, software, platforms, programming, backend, frontend, networking, cloud computing, online/offline, etc. You might as well consult an IT Engineer for help.
