Deloitte Manager interview questions

HR experience: I received an email from HR to provide available days, I gave them 4 days and then I had to wait for two weeks until they came back to say they could not confirm as the interviewer was not available. I called twice HR to arrange new dates and the third time I called I left a voice message and also send an email. However, I was never called back. Neither call nor an email. Three days after my call, I sent them another email where the HR person told me that I could have my interview the next day which was impossible for me to give that short notice to my work. I explained that and then he said that he would check and come back to me. Guess? He came back 3 weeks after! Also, I asked him to know more about the process and he cc 2 people on the email to explain the process to me and none come back for around ten days, even if I had sent them 3-4 emails. Horrible HR experience and very unprofessional attitude with lots of delays and bad manners. Interviewer experience: The next surprise was my interviewer! I checked on him on social media and found him with naked people. Then I went to the interview and the guy could not remember the questions to ask me, he used slang language all the time and felt like he was under drugs! A week after I received an email from HR that didn’t pass without any reason. I was curious to know the feedback even if I felt it would not be productive from a person like that. I thought if deloitte can hire these people without proper checks then this is not the right place for me. It’s so true that the recruitment process is a two-way approach! I would never apply to this company again. PS I have offers from two consulting companies bigger than Deloitte which most importantly reflect the values and culture I want to follow.
