Qualtrics Software Development Engineer In Test (SDET) II interview questions

Recruiter reached out for the SDET-II Developer-Platform Ecosystems position. Scheduled an overview call with HR to screen. She went over the position, TC, benefits, etc in addition to asking questions why I'd like to work there and my background. Then went over the process, which is one tech screen and then a multi-hour panel. Tech screen was set up and was hosted by someone at the HQ location versus the one I was applying for - which is very different culturally (traditional, "basic", christian) Went over background and asked 1 STAR based question. Took 15 min. Then was asked a HackerRank type question for max palindrome in a string type question. I solved it within the time but not with all the test cases passing. I'm guessing based on being totally ghosted with no feedback that, if you don't clear that bar with a solid 100% TC passing, you won't get considered for a second thought.
