Deloitte Software Engineer I interview questions

This was for Deloitte New Zealand. 1st interview was automated video recording with 5 questions. For 2nd interview, they gave case study presentation to complete before the interview, during the interview seemed obvious that are exploiting candidates to get some free work done via the presentation. Once you explain the presentation, they abruptly finish the interview without so much as a polite conclusion. Very cheap tactics by Deloitte New Zealand to get free work done which takes nearly a day to complete, dont bother wasting your time with this company.
