There are some absolutely ridiculous qs I've been asked like this and they've all had no followup question to illuminate why it would have been relevant 1. what version of java do you use? we used 8 at the time 2. what is the engine and version underneath your sql db?this was not for a dba role, just standard backend engineer 3. why did you use python instead of r for x project? this was about a gui automation script

>You can often tell an inexperienced interviewer from the extremely domain specific question they ask which _they_ are familiar with.

Lol a bit touchy aren't we?

Like I said, it's not really relevant in today's languages. It was for a Delphi/Pascal position. If you do any type of database code (like T-SQL), you would also know it. If your experience is mainly in C type languages, everything is a function so it doesn't apply.

If you hired a guy for a Delphi position who didn't know the difference between a function and a procedure, you hired the wrong guy.

  procedure Hello;
  begin
    ShowMessage ('Hello world!');
  end;

  function Double (Value: Integer) : Integer;
  begin
    Double := Value * 2;
  end;
