I interviewed at Aston Carter in London. Most of the interviewers I had didn't seem very interested in what I had to say. The interviews were very structured and monotone as they were following a set of questions which were repetitive. This made it hard to make the interview exciting and interesting as there wasn't much interaction.
I had 4 interviews in total, including a telephone interview and I was interviewed by 6 people in 2 different locations. This was a very intense and long interview process.
