Very long-winded. I had three calls with people from three different countries, then asked to attend in person. I was at their London office for over 3.5h. I had to take a half day from work. Everyone was happy and polite but what a waste of time to have to meet the entire team like that. The time I spent on all interviews combined was 7h. I was not offered the job so I asked for feedback but was told they do that. What a waste of time.
