1. On the intro call, there were general discussions about past experiences, skills, etc. No tech questions were asked.
2. The offline tech (ML) task was quite challenging as it had to be completed within a particular amount of time.
3. The tech interview afterward was quite good, the interviewers were very supportive, they were trying to bring down my stress, and were helping out to come to correct answers. My level of expertise was just not the one to answer these properly.
