I applied through college or university and the process took 3 months - interviewed at Opera Solutions in September 2013.
Interview Details – Applied through college career posting. On campus first round and in-office final round; standard 2 half-hour interviews in each round. First round mostly behavior/fit questions with a bunch of brainteasers; second round all case questions. Interviewers are very nice and easy to talk to and questions very fair (in my opinion), but it took them an excessively long time to inform you their decisions (first round in early October, second round in late November, decision in early/mid January).

Interviewed at Opera Solutions
Interview Details – Interview consisted of giving a technical talk about my previous research to a group of ~15 people, then 3 closed-door meetings one-on-one, first with a potential boss and secondly with two people who would have been peers. After interview, an HR rep told me by email that the feedback had been positive, but I didn't hear anything else back so I guess she was just blowing smoke.

I applied through an employee referral and the process took 2 months - interviewed at Opera Solutions in November 2012.
Interview Details – First round interview began with two phone calls, each around 30 minutes. First was a business case dealing with churn and how to stop it for an online dating site. It involved some easy math and you had to talk about ways to stop churn and data you might want. The second was a fit interview, all pretty basic stuff, like why consulting, etc. In person interview about 2 weeks later. It consisted of 3 interviews, each about 45-60 minutes. First interview had some fit elements and a brief case about credit card fees and attrition. Second interview was a supply chain case (which was very confusing if you're not familiar with the terminology, and the interviewer was seemingly very pressed for time and really rushed me through it, which I think took away from the interview overall). Final interview was mostly fit with a brainteaser thrown in. Heard back from them about a month or so after my in person saying I was not going to be made an offer.
