IBM Entry Level Data Scientist interview questions

Round 1: Received an invite to complete an online video interview. Interview consisted of recording and typing out short answers to technical questions.

Round 3: Interview with a senior member to discuss potential role and location preferences. Not a weed-out interview at all. Round 4: Invite to an in person event with several other candidates. Event was mainly about company culture with a case study thrown in. Offers given out shortly after event.
