Deloitte Data Scientist interview questions

1st round : behavioral questions, very standard. 2nd round: technical (present a data science project you worked on). can be any topic but has to be related to data and some models, some follow up questions but not difficult

Extremely arrogant interviewer, he was 10 minute late, i explained about my projects , post that have mentioned 2 coding questions. I solved both of it but he felt that my approach could have been simpler
