Initially the process kicked off really well but then they rejected me giving a baseless feedback. There are a whole lot of layers in their interview process. I wanted to work at ThoughtWorks at every cost. I went through a http hunt game first after which I was told to prepare for next round. HR suggested me to read a refactoring book by Martin Fowler which I did. Next round was first technical round and they made me explain everything about my current project which i did. Feedback for me was excellent till this point. For second technical discussion I was told to prepare a project based on webservice (since I had never worked on it) and they wanted to check how well I can learn it. I prepared a production ready project for rest with all the necessary modules and explain each one of them. Eventually, I was told that they are looking for a different profile for me. after two days I get an email stating feedback - at my experience level, they expected more depth in web internals (which they knew I was new to). It's still a mystery to me that why did they make me go through all the rounds when I had clearly mentioned I had no experience in web. I was told they look for oops concepts and core java understanding and i dont see how rest apis became the point of rejection. Overall a very disappointing and tiring process.
