J'ai postulé via un recruteur. Le processus a pris 2 semaines. J'ai passé un entretien chez NODAL EXCHANGE (McLean, VA) en mai 2016
Entretien
It was a 4 hour long interview with 4 individuals. Each round or section took roughly around an hour. Each round starts with an interactive test/exercise and then is followed by some behavioral questions. 2 rounds are very simple. They basically come up a use case situation and wants to you go through it with them. In these 2 rounds they're basically trying to see whether you can work along with them and how apt you are coming with business solution ideas. The last 2 rounds are case rounds. One case interview is going to be most likely a cost-benefit analysis and the other one a more quant heavy problem or case. None of them requires sophisticated arithmetic skills. GMAt math standard is enough.
