IBM Researcher interview questions

I was asked to join a conference with 6 people interviewing me. Not everyone was active. However, they asked me a few questions about my resume. The position was New York based.

Telephonic interview with questions based on Machine Learning and NLP (these were relevant to the projects being offered). They also asked about my previous projects enlisted in the resume which were again relevant to ML and NLP. They also asked if I would be comfortable in programming in Java and what other languages did I use.
