There's a virtual onsite called the "power day". It was one of the better onsites I've had. The power day takes place fully remotely, and involves the typical kinds of challenges and interview questions you'd get from Square or Stripe.
Interview questions [1]
Question 1
System design questions - how to architect a service
I applied in-person. The process took 2 weeks. I interviewed at Capital One (New York, NY) in Jan 2023
Interview
Meet with different teams throughout the day. Usually two people at a time but sometimes just one person. It was the typical "behavior" style questions, hypothetical questions and programming type questions using the language of your choice. Very little questions about me but there was always time to ask questions.
