Phone interview with HR for 30 min followed by a 3hr on site process composed of 3 steps - interview, assignment, assignment review. The 1st interview included sql and list comprehension questions and basic into questions. The assignment was to show an eda and design features based on the fraud / not fraud data set given. then 1 hour session to discuss the assignment. No real ML related question were asked, projects and such. no algorithmic questions. The interview felt like a data analyst interview at the ml level required but then in the end they asked about production level coding (but did not test). The overall feeling was that they don't know what they are looking for and gave a confusing vibe. They did not get back to me for 1 month after the interview.

I had a short phone call from the data science team lead where I briefly scribed my experience and he told me some details about the company and the role. The second interview was 3 hours on site divided into two equal parts - statistics and machine learning questions and hands on exam. The third and fourth interviews were with the data science director and chief data science respectively. Both of them were less professional and more personal
