Sixt Software Development Engineer II interview questions

Total 5 rounds of interview: 1) DS/Algo 2) Machine Coding / LLD 3) System Design 4) HM 5) HR 6) Online coding test (super easy) Recruiter was updating with feedback within 30 minutes of each round and asking for slots for next round. I was ghosted after HR round. Please don't take this company seriously. Management has no idea whatsoever. There is no point rejecting a candidate after 6 rounds of interview without giving any feedback. Although the interviewers were very humble and helping , they themselves were struggling to understand my given solution. I had to explain the solution of a coding problem for 20 minutes to the interviewer.
