They asked for a brief overview of your current work and the types of projects you worked on, and the different types of languages you are familiar with. The 1st round was a behavioral interview, but I believe it would be a case study afterwards in the 2nd round.

3 rounds of behavioral interviews on zoom. The interviews were relatively short at ~30 min each. One with manager, director, and a group interview with extended team. Whole process was ~1 month from the first time the recruiter called.
