Credit Karma Engineer interview questions

I had several interviews throughout the day, either one or two people interviewing me at a time. The first session was good/normal, though not my best. The second session they asked me pretty much the same questions. The third session was one on one, the interviewer was hard to understand and his questions didn't make sense - he was asking me questions that were completely irrelevant. The fourth session was also one on one and this one was my best. Overall the day felt rushed and confusing, and the interviewers didn't seem prepared. It seemed like a neat office otherwise.
