Deloitte Intern interview questions

Phone discussion with HR, around 40 minutes, we have agreed that we will continue with the technical round in their office, for this we agreed in date and hour, amd she told me that she will send a confirmation to my email address. No confirmation received, couple of days before the date we have agreed, I have tried to contact the lady from the hr but no answer neither on phone or email. Very unprofessional..This was abou 4 years ago.

Quite smooth and straightforward. First, you go to an AC and grind out a case study with a few other interviewees. After the AC, you have an interview with someone on the team that you applied for.
