I applied online. The process took 3 weeks. I interviewed at American Express (New York, NY) in Nov 2013
Interview
Waste of time. The experience of interviewing with American express for the data scientist position made me wonder wether being a data scientist means that you are a geek with no decent people skill. They treated me in a very unprofessional and unaccepted way. They did not care about showing up on time for interviews. The worst part is that they threw random questions at me. All of the questions were something you could find online for typical interview questions for quantitative positions. I guess they did search for something online before the interview.
Interview questions [1]
Question 1
I think that one of the questions they asked was just have no answer. I seriously doubt the validity of the question.
I interviewed at American Express (Gurgaon, Haryana)
Interview
It was a fair and structured interview, focusing on SQL, ML fundamentals (boosting, imbalance), and business cases like fraud detection. They prioritize logical thinking through puzzles and guesstimates over complex coding.
