IBM Data Scientist interview questions

Q & A with an automated system. Half of the questions 16 in total, required a camera. The others were typed. You are given a question and then given about 2-4 minutes to prepare your answer. The allowed response time varied between questions. None of the questions were particularly difficult or convoluted.

I had 2 phone interviews and 1 aptitude test which is the IPAT. In the first interview the questions were mostly about machine learning, different algorithms and some in depth questions into it. In the second interview I was interviewed on Spark, big data stack like Hadoop etc, some Java questions.
