I applied through a recruiter. The process took 3 weeks. I interviewed at Capital One (San Francisco, CA) in Feb 2022
Interview
Look at the top review. They are going to ask you how to design a smart meter for multiple apartment buildings, then they are going to ask you 2sum closest to 0, then they are going to give you code and ask you to talk them through it, then they are going to give you a behavioral interview.
Another thing: The people who interview you are not going to be the people you actually work with
Oh, if you pass codesignal. You need something in the range of the 700s or higher, which is more forgiving than most companies that use codesignal
Mini-rant: If you are going to ask everyone the same questions, then base your decision on whether or not they got the correct answer, then the people you hire are going to be the ones who memorized leetcode/glassdoor answers, not the ones who actually solve problems

Interview
For internship/recent grad, the process involved a phone call followed by a 3hr session consisting of technical interview, case study, and a behavioral interview.
The technical interview has a design problem and an algorithm problem with multiple parts. Case study incorporates pseudo-coding and thinking of edge cases around a business problem.
