a zoom interview with leetcode question second step was 8 hours in the office, solving a real life problem, allowed using ai tools and then went over design and implementation

The interview process was fun , first assignment was a technical task that u can do in go or java can use AI . if you clear it(idk how u can not clear this) , you move on to the second interview with 2 of sap engineers classic leetcode style with a bit of system design they even left the room so i can code up without feeling pressure they were super nice. each interview was 3 hours, but what was weird was the recruiter :- 1) doesn't answer mails i send totally ignored. 2) after the second interview i got positive feedback and told me they will get the manager so we can do the interview now but later the recruiter came and changed his mind ghosted for a week then got rejected. the question is leetcode medium nothing hard i feel like with this process too many people get to later stages so they have to reject "randomly" overall easy process just bad recruiter in my opinion.
