I applied online. The process took 2 weeks. I interviewed at American Express (New York, NY) in Jul 2013
Interview
Short, took an assessment and depending on the grade you received a follow up. The test was about an hour and a half to two hours long with business accumen questions.
Fueron varias fases, pero no especialmente complicado. Una de las entrevistas fue en inglés, que sí que se requería un nivel más alto, por lo demás fueron entrevistas promedio. Eso sí, las condiciones bastante normales.
Basics in sql, python and tableau. Some questions from case study. Easy to crack. Total 3 rounds of interview. Final round questions were focused on regression like assumptions, related to coefficoents etc
