I had 2 interviews - one with the London team on phone and one in person interview in New York. I got the results in 3-4 days and was requested to join as soon as possible.
I applied through college or university. I interviewed at Barclays
Interview
Campus recruiting. Two rounds in a row. Two interviews, each one is half an hour. One will ask you technical questions and the other ask you behavior question. One week later the HR will call you about the result and give you offer at that time. You only have two weeks or so to decide.
Interview questions [1]
Question 1
The technical question, I didn't really get it then.
I applied in-person. The process took 5 days. I interviewed at Barclays in Jul 2010
Interview
Behavioral Interview process, standard questions around prior experiences, successes and failures. also examined my style of management, working with difficult people etc. All in all, the interview process was very straightforward for investment banking
