  • Set the interview expecation like what they're being assessed for, example you can mention that this round is for LLD/HLD, DSA, JS basics or so.

Assessment

(Make sure there that you've the points in your mind to ask in way which is unique and written somewhere on your machine and pulled up on your screen. Always remember that knowledge and its application are 2 separate things completely. Always try to look for candidates who have better application skills and the ability to learn quickly)

  • Ask candidate to share their entire screen if required to before asking the question.
  • Share the interview question over chat in case of virtual meeting instead of dictation
  • Ask the candidate if they've understood the interview questions.
  • Aks the canidate if they've queries about the interview quesitons.

Interview as a Service platform evaluation

Queries

  • Are there screen recording available of the candidate's machine?
  • Are there webcam (with audio) recording available of the candidate's machine?
  • Can we prevent copy paste or at the very least view the list of copy pasted texts without alerting the candidate?
  • Can the candidate write the code in cloud (like CodeSandbox) where we can monitor them?
  • Can the candidate write code in the programming language / framework they are comfortable with?
  • Can we view reports showcasing code quality & code coverage?
  • Can the interviewer set the different time limit (including no time limit) on questionaries?
  • Can we prevent or detect tab switching?
  • Can we provide Google search with control over what is being searched or restrict to documentation search only when the candidate is writing the code live on cloud editor?
  • Can we have the interview questions in image format so that candidate can't Google it easily by copy pasting it?
