Ripple Software Engineer New Grad interview questions

I got ghosted. :( So, I applied and finished OA. After that, HR contacted me and we set up the first technical interview. Then, during the technical interview, I struggled a little bit and eventually solved the problem. I sent a thank-you letter and asked for a feedback. But, no response.. A friend of mine worked at Ripple during summer. He told me about the projects he worked on and I thought it would be nice to work at Ripple. Please don't ghost.. Just a simple thank you and you didn't get the offer might have been kinder. Sincerely, Just a regular new grad software engineer.
