I applied through a recruiter. The process took 2 weeks. I interviewed at FDM Group (London, England) in Nov 2017
Interview
I was contacted on the phone and then told to do a competency test and then a further video interviewer. The recruiter was very excited and called me straight away saying I got into the final stage which was the assessment centre. However once I got there I realised that I would essentially be forced into a two year contract with a £20000 fine if I was to leave early or refuse a job placement. HOWEVER. If you are geographically flexible and willing to relocate for short periods of time for not very much money this is a shot worth taking as you may be placed in companies you could not have got into otherwise. Very good for your CV.
It is a four stage process first is a phone interview, a video interview, some psychometric tests that you do online attached to the video interview link and then the final stage is an assessment centre.
The interview process was extensive but overall a good test of my skills to see if I could handle the job. It was 3/4 individual interviews and aptitude tests for Maths & English.
Interview questions [1]
Question 1
An example of one was "Tell me a time when you had to work to a deadline"
Psychometric tests, video interview, face to face interview. Not difficult. Some sections are long and require concentration. That's to get in to FDM. Once you're in, you have to do the same to get in with clients.
