75F Senior Software Engineer interview questions

Interview process had only one round, in which 95% questions I answered were correct, still they gave feedback after a week that I am rejected. Worst part of interview process is they keep interview on weekdays and then even when the candidate is 95% correct, they reject them, so stupid of 75F,Who the hell expects 100% perfect candidate. Even HRs from big brands donot, 75F HR should check LinkedIn and learn. They have 0 consideration for the candidate's time, the money spent in coming for interview and skill. Useless company, zero facilities but attitude is even more then Microsoft or Google.
