KPMG Vacationer interview questions

I was asked why I wanted to work at KPMG, to introduce myself, and then I was asked 3 more HR questions. These were a time I have been put in an unethical situation and how I dealt with it, a time I have improved a process for my team, and a time when I knew I wasn’t going to meet a deadline and how did I ensure that the quality of work was still up to standard.
