What are interviewers trying to know when they ask the following question : Have you developed/supported mission critical applications ?
IMO
Have you developed/supported mission critical applications?
In my opinion, all applications are mission critical to the organization making that application. For exexample, Gettinggetting information from the Mars rover may be mission critical to a Govt.government project, and getting users to sign up for an email service is mission critical for an email hosting provider. To me, all applications I work on are mission critical to my employer/client, so I am not sure how to answer this question either.
If someone can help me understand what the interviewers want to know about a candidate by asking this question, it would help me answer the question in a better way.
