ZIGRAM Data Science Intern interview questions

Interview was a smooth process, although it took a span of month for all the process to be done. There were 4 rounds, first was resume screening, second was the aptitude test which was quite simple and had a lot of topics like quant, logical, english, python, tableau, powerbi, NLP, etc, third round was the technical interview round where they asked questions about python basics, probability questions, sql joins, and machine learning basics like linear regression assumptions and concept. Third round was also a technical round but more on the logical side, I was asked to explain linear regression in very simple terms, situation-based probability questions, and some puzzles with no definitive answer but the approach was assessed..this round was with the team lead so they are looking for a general fit for the team also.
