Thoughtworks interview questions

I have never faced such a ridiculous interview in my life. They had given a problem to design a solution. The problem they had given was not a great and complex problem. I had given a solution following the SOLID principles and Object Oriented concepts properly which is highly extensible. I have around 12 years of experience in total and I'm completely in the field of designing applications for last 6 years. After I had completed the design a lady came to review the solution. I think that lady was expecting a simple and straight forward solution which any layman can design and the solution which I had given had gone over her head. She was not able to understand the complexity of the design whhich I have made. She had given me some more requirements to extend the design which I could easily incorporate in the solution which I had given as my solution was following all the standards of SOLID. But still she did not like the solution and argued with me about some base less points and still I was able to overcome all her arguements. I think she took everything personally her ego got hurt a lot and I was through ;) :P The HR was claiming the company to believe only in quality but after the interview experience and seeing the technical abilities of the interviewer all her claims had proven to be false. The only thing I liked in that company was the Security person who would always ask you to have lunch in their canteen before leaving.. :P :P So, guys if you have a lot of time to waste you can go Thoughtworks for attending an interview.
