Thoughtworks Software Engineer interview questions

Telephone interview. We talked about my experience and they did some questions about my resume. They explain me about the company philosophy. I'm waiting the technical interview. They will send three problem to me, I need to pick one and propose a solution.

I had a skype interview with one of their staff in late April 2017. I only completed the initial interview. The interviewer asked me why I had applied to ThoughtWorks . After I answered that question she informed me that they have just one project on at the moment and it was to convert C# to Scala. I was surprised as Scala was not on the skill sets mentioned. I was also informed that they want people who want to be available to change their skill sets continuously. I said I had to have a think about it - as I know very little about scala. That's where the call ended. The interviewer seemed a bit defensive - perhaps she had gotten negative feedback from others.
