Data science internship first step was just an OA coding test. First was SQL and then data manipulation in Python.
Not too bad but took some time. Good luck !
I applied online. The process took 2 months. I interviewed at IBM (London, England) in Nov 2019
Interview

Then I had to a prerecorded video interview. Then I was invited to a final interview in London. The office was really nice because they were weworks offices
I applied online. I interviewed at IBM in Sep 2020
Interview
Received both a hackerrank coding assessment, and a cognitive assessment. The cognitive assessment was a number of quick games. Coding assessment was a Python and a SQL question. I completed all portions, and passed all test cases in the OA. I never heard anything back following the completion of those part.
