GoFundMe Devops Engineer interview questions

Applied for the company at early July, got HR call at the end of July and then set up for phone interview at the next week. the next day got a call from the recruiter that the phone interview went well, help me setup onsite interviews. and then the recruiter went ghost. 1 week or so passed, she emailed me said the team that I interviewed was no longer hiring and passed me to another team recruiter. This recruiter instead of sending emails she loves making calling, while I always missed the calls, and she never replies email. finally I save she number and got her call. she asked me if i still have interested in gofundme she can set up phone interview with me. it's already late Sep when I phone interviewed the second time with gofundme. passed the phone again. setup the onsite interview. 2 technical sessions easy LC questions, and worked out those. 1 behavioral. 1 with hm. instead of system design questions, hc only asked questions background questions. I thought i would get an offer. while the recruiter went ghost again. 10days later I got a rejection email.
