Goldman Sachs Software Developer interview questions

Associate having 5 yoe asked me 1) Hashmap question with follow ups 2) Graph question with follow ups Made me write my own test cases Interview went well all the hidden test cases passed still rejected.

Terrible, zero responsiveness. Interviewed three times and ghosted every single time after interview. Interviewer also did not know his thing and was giving wrong corrections. After the interview, did not bother to get back to candidates at all.
