WebAble Digital Senior Machine Learning Engineer interview questions

They provided a google meet link to all candidates so it was a group interview session. They took a coding test where two unknown GitHub repositories were provided and 15 questions were asked to answer. How did they expect me answer questions based on GitHub repos I had never seen? Moreover, each question had only 2-3 minutes to answer (the countdown was also buggy). Very poor interview experience. I am pretty sure they did not even know what they were looking for.
