At first, I didn't get the offer even though the process was easy. However, six months later, the company called me back and offered me the job. They initially told me to prepare for SQL questions, but on the day of the technical interview, they unexpectedly asked me Python questions as well.

It was a 2 stage interview process, starting with HR and then moving to a technical interview. It was pretty standard for the area. The interview was pleasant and short. I got an exam with technical questions, including SQL queries.
