I sent an application at the beginning of August. Around the middle of October, I receive an email inviting me to a 30 min Phone Screen with a recruiter about 2 weeks from the date of the screening. A week later I get an invitation to their Power Day with a time slot pending after the holidays. Around January, I get an email to officially schedule my Power Day. This consisted of a Job Fit, Behavioral and Case Study. A week later I received my offer! Overall, I had a very positive experience! Overall, the app process took 6 - 7 months but others had shorter time intervals so your mileage may vary. Best of luck!

Took over a month to hear back from them after I submitted my application. Then took another month to schedule the power day after the phone screen. Power day was alright but I feel like the case interview prep they send you wasn't like the case interview at all.
