Short Skype interview with potential line manager so they could get a feel of who I am as a person. After this I was sent some online psychometric tests to complete. Due to my results of these tests I was invited to a face to face interview. This interview was long and tough, by far the most difficult interview I have ever been to. I was interviewed by two senior members of Martek separately, they really didn't give anything away so i had no idea how i had done, i in fact came out of the interview thinking I had failed! However was offered the job less than 2 hours later.
