Capital One Senoir Software Engineer interview questions

I applied for a frontend position online. Contacted by a recruiter within 2 days for a phone screen. 70 minute online assessment (CodeSignal) with 4 questions (2 easy, 1 medium, 1 hard). Some simple array navigation, a 2d array / nested loop, and an undirected weighted graph question I couldn't figure out. Seems like you just need to get 50%. "Power Day" was 4 back to back interviews via Zoom. First tech interview was an easy CodeSignal prompt on forms in my JS framework of choice, talked about some JavaScript syntax and performance. Second tech interview was a frontend design prompt to build a SPA. Questions around component structure, routing, data flow, Redux, API calls, and more in depth knowledge of frontend frameworks. Behavioral interview, pretty straightforward STAR questsions. The interviewer didn't seem to like my answers. Not sure if he thought I made up the scenarios I provided, but he gave me push back on most things I said. Seems like they just want to get more out of you to write down for feedback. Case interview walked through a business case for calculating costs. First, think of requirements and considerations. Second, talk through some example calculations and a formula. Finally, I had to identify and fix the algorithm in a faulty code sample (no formal testing, just talking through it). Most interviewers were friendly and had good things to say about the company. Was rejected for the original position I applied for, but was contacted a week after my interviews to meet with hiring manager for a different team.
