I applied through a recruiter to join Deloitte Dublin. I was invited to a face to face technical interview and this was the worst interview of my life. The interview was held in London. The reason why it was the worst interview of my life is that the interviewer was late by 45 minutes. The interview was due to start at 8 am and finish at 9 am and I had to go to work after that. The interviewer apologised but if I was the one who had been late I would've been walked out of the office. He carried on with the interview and asked questions about C#, SQL, OOP, threads and general software engineering questions and some of his answers where wrong but he didn't know so he thought my answers where incorrect. He had about 10 years experience and I have only 2 years experience so he should have known the right answers but he didn't. As a result he said I had a few technical gaps which I did not. I was very late for work because of his lack of punctuality but when I explained to him that I would be late to work he didn't even apologise or show empathy. he wasn't even wearing a tie and he had rolled up sleeves in the interview yet he gave feedback that I was a bit too informal yet I had a full suit on and was very professional. I have worked for a top 25 FTSE 100 company and a world top 20 global IT firm and have outstanding performance at both yet this guy thought I wouldn't be good enough to work at Deloitte? After I realised that these big four firms do not want the best talent out there and are looking for people who are just good at making power point presentations and have the same level of incompetence as them. Stay away if you are a top flight software professional!!
