I applied online. The process took 4 weeks. I interviewed at Capital One (McLean, VA) in Oct 2018
Interview
As everyone else mentioned, there is a background check (easy), hackertest (easy), technical phone screen (on machine learning), NYC taxi challenge (easy but time consuming), and then onsite. People are extremely friendly so I left with a positive experience. 5 interviews on site plus lunch.
Their role play on-site is ridiculous though. They gave me 10 pages to look at and I had only 15 minutes! seriously? I need 1 hour to interpret 10 pages of data!
There were two case studies. One about machine learning, and one like a youtube video they have posted. Overall, I enjoyed the company a lot. People were extremely friendly.
Sometimes, it makes me think, how can someone score well in all these rounds of interview given the stress and brain freezing. I guess there are people who can do that!
I went through initial HR screen and online assessment, both were on the easy side. OA is data wrangling with pandas, CodeSignal. Waiting for recruiting manager interview. nothing too crazy.

First, there’s a 30-minute call with the hiring manager, focusing on background, experience, and role fit, with no technical questions. Next is a take-home assessment, to be completed within 7 days, where you’ll build an end-to-end data science solution from data loading to model creation and evaluation. Successfully completing this makes you eligible for the final interview stage, called 'Power Day.'
Power Day consists of four 1-hour interviews:
Case Study: Includes questions like assessing if a car company should launch a new product. Check out the 'Hacking the Case Interview' YouTube channel for tips.
Roleplay: You’ll receive a presentation (PDF/PPT) to study for 10 mins and explain and discuss with the interviewer about what insights you can establish from that.
