Capital One Software Engineer I interview questions

HR Screen Phone Call General Coding Assignment with 4 questions 4 hour long Power Day Recruiter was very responsive during the initial stage, then completely ghosted after asking for my availability for the Power Day interview.

Scheduled an interview with the recruiter, but they never called at the scheduled time. No response to follow up emails, calling, or voicemail. Talked with my friend that referred me and he told me that the recruiter is still consistently online, just ghosting me. Extremely unprofessional.
