TD Data Science interview questions

I can describe the interview experience as a Data Challenge type: First part: Coding/SQL interview The first part of the interview (coding test) included 2 SQL query questions and one Python algorithm question. Second part: Statistics and ML interview For the ML interview, I was asked general questions regarding the end to end of more training, how I would do your data cleaning, feature engineering, mode selection, model performance over time etc. There won’t be a coding. Requirement or anything hands on. Third part: History and fit interview This part will focus a lot on your resume and I was asked some standard behavioral questions.

On site interview is mainly focusing on coding and project I have experience.very nice experience.we talked about 1.5hour about detailed information. But when I received the decline letter with one research survey
