Tesla Charging Analytics Intern interview questions

Went through 5 rounds, starting with a general interview, a coding challenge, a review of the same, an interview with a manager, and one with an HR person. The all interviews were quite comfortable and somewhat informal, as was the email communication. The coding challenge was based on a set of first name data for the US since 1900 and asked about forecasting and clustering analysis. It was requested that no more than 5h would be spent on it.
