Deloitte Data Science interview questions

the interview was difficult. they asked me regarding my machine learning skills and data science skills. They also jumped to asked few questions about sql and dbms. Then they asked me few puzzles(3). Then they gave me a case study, where they gave me a data set and want me to do EDA

I had first round only where I was rejected. First round was technical round, where I was asked Python questions on tuple, list, mutable and immutable objects. For lateral hiring, I was expecting questions on solutioning and business side but was asked questions on how to make a tuple. The round lasted hardly 15 minutes.
