Interview Process

IBM Data Science team uses HireVue to screen candidates. The challenges happen on the Hirevue platform setup by the IBM Data Science team. There is a mix of questions which require short write ups, free form explanation of concepts, video responses and coding solutions. That is followed by onsite technical and behavioural interviews. The on site sessions are with people from Information Design, Statistics and Machine Learning as well as Management.

Reflecting on the Questions

IBM Watson has been around for a long time. The interview process is very rigorous as it tests multiple aspects of data science. Fundamentals and coding are very important. Interviews also focus on projects based on the candidates resume and drilling deep on decisions made during those projects and the rationale behind them. Serious hard work is required to ace these interviews.
