Colloquio difficile
Candidatura
Ho presentato la mia candidatura online. La procedura ha richiesto 3 settimane. Ho sostenuto un colloquio presso Capital One nel mese di mar 2015
Colloquio
the interviewer started by talking about the internship, the responsibilities and duties, and possible promotions.
then he started the techniques questions part. he asked about 5 big questions, all relevant to statistics. I would say at least mediate level of statistics. The easiest questions is to interpret a 95% confidence interval; while the hardest one is asking how to deal with a very large data, like what is your thought process and what techniques you might want to use. I did not get a feedback on my answers so i did not know whether my answer is correct or not.

Hiring through campus website. Got the first round interview 4 days after application. After the interview, wait 2-3 days to know the whether can be selected for the 2nd round interview. The second round interview is back-to-back interview without cases. A short case interview for about 20 minutes for the first round. Very similar to the one posted online as the example.

First round was phone interview, totally 5 questions, 4 of them were related to basic stat concepts but given in real world background. Got notice about the final round about three hours later. On-site was much harder than the first, more business focused rather than statistics.
