I hope I understood correctly your question

You wanted to be sorted based on first name and age of the questions and then pageing the data based on that sorting

;with _listQuestion as(

        select *,case 
                     when Title='FirstName' then 1
                     when Title='age' then 2 
                     else 3 end as InterviewOrderNumber  
        from Questions
)
select *

        select a.*,b.LocationName,c.InterviewOrderNumber,c.Id as iq ,c.Title
        , row_number() OVER (  ORDER BY InterviewOrderNumber ) AS rw

         inner join Interviews b on a.InterviewId=b.Id
