I got an email inviting me to an interview at their London Bridge office where I met two people. The interview was enjoyable and the people were very friendly.
At the second interview I had two new people interviewing me. Both were also really friendly.
Unfortunately I did not get a call back after the second interview. I followed up via email and got a response saying that they would get back to me. This has been over a month ago and I am yet to hear a response which is disappointing.
