Technical Architect Interview Questions – Part 2

interview questions

Following is the list of questions that were discussed by me with some of the guys appearing for the position of technical lead or architect, in last few months. Please feel free to share your opinion on them.


  • Define the roles and responsibilities of technical architect, application architect, solution architect and an enterprise architect?
    The reason I asked this question was that the interviewee ended up mentioning all of these roles while introducing himself. And, while answering the question, he was unable to clearly define these roles. As an advice, please take care of mentioning about your role when attending the interview for the role of an architect.

  • How is the recent turmoil in Javascript world with frameworks such as Angular, Knockout, Emberetc, would impact the overall architecture of upcoming web applications?
  • Define REST by describing Representation State Transfer? Interestingly, I have found that many were not able to clearly define in terms of “Representation State Transfer”. :-)
