I was referred to the IBM Watson Health Group - Innovation team by a previous coworker who works for IBM now. I talked with the HR on the phone. It is an information interview for me, but certainly she took it as a screening. I heard that she was typing while I talked about my research. She then asked a data scientist to give me a technical phone interview. The technique interview was not too hard, but certainly you need to prepare for it because she asked about the detailed questions on data modeling.
