There were two phases. In the first Zoom interview, they asked me some general personal questions. A couple of days after the first interview, they sent me a small data analysis project that took 4 days for me to handle. The second Zoom interview was a couple of days after I completed and sent the project. They asked me some questions about the project, e.g., how did you handle the unbalanced data, what is data leakage, and so on. A couple of days later, they asked when I would finish my PhD. Finally, I did not get any offers.
