ECI Systems Engineer interview questions

Had 4 stages to the interview, last stage was a face to face where I was told it would last 2 hours and they would talk about a lot of things inc work experience. Interview was only technical questions (which I got all right). It seemed as if the 2 technical interviewers weren't really bothered or interested. Needless to say I never heard from that agency (ampersandconsulting) not even a call or email, which in my experience is the default behaviour from agencies.

Unprofessional, both interviewers were late and showed little interest.not sure why they even bothered, I wasted a lot f money and time for this 45 minute conversation, still puzzled over whole process.
