I applied through an employee referral. The process took 2 months. I interviewed at Tripadvisor (London, England) in Aug 2012
Interview
Total of 11 interviews till the final stage, unfortunately I was not the chosen one.
Too many interviews and poor communication between HR and interviewers.
In my case, it is the process which did not seem very good because of miscommunication between managers, HR department in UK / in the US and I.
