Deloitte Frontend Software Engineer interview questions

2 rounds of technical, and then two rounds with senior management. Technical interview was a breeze, childishly easy JavaScript questions and I had a feeling the interviewers didn't have a very good grasp over what they were talking about. Average waiting time between interviews were around 1 - 1.5 hours of waiting around, which wasn't really a pleasant experience as the HRs were totally useless. They would say, they would get back to me in 2 minutes, but usually take more than an hour or so.
