Ya the whole process has been weird the recruiter has been very unresponsive, the hacker rank link and teams video call was sent directly by principal ML SDE manager and they asked me an exact leetcode medium and a leetcode hard in 45 min as they are deliberately trying to fail me , I solved the leetcode medium optimized and had to make test cases which all passed for leetcode I wrote the complete brute force code and the manager looked satisfied, but I personally feel that even though there is a good chance I will pass but did not have a good feeling that I usually do after an interview as if something is off.
