Verily Software Engineer interview questions

Interview seemed shady, as there was no contact of recruiter straight inital coding round. the interviwer was not ready with the question and was underprepared. If there is a person that can solve the leet code style provided question under 30-35 minutes. I respect you, and you are a GOD Level programmer. The question provided was designed so that you will fail. My interviewer provided me extra 10 minutes, was able to write the complete code and implement the algorithm, but the test cases did not pass. 3 weeks later, got a generic rejection, and only to apply after a cooling period which is a year. The company head count has not increased, It felt as if the interview was taken just for the sake of buring time and money of the interviewer and the candidate.
