I applied online. The process took 3 months. I interviewed at Bain & Company
Interview
Processo molto lungo ma di ragionevole difficolta'. Ben calibrato per testare vari aspetti del lavoro di un Data Scientist. E' composto da un test di programmazione/creazione modelli, 2/3 interviste tecniche e 2 colloqui con il management

Question 1
Tre fatti importanti che ti hanno portato a scegliere di diventare data scientist
There were 6 rounds (elimination based) in total spanning across a period of 2 months. Despite all the rounds going well, I did not get an offer nor any feedback despite requesting for it, given that I have invested so much time into the process
Interview questions [1]
