Its friday so why not. Most pointless interviews you've had.
1) Perm job years ago. I had all the skills on the job spec on my CV. Spoke to them - they were going to train me in a new technology. Went for tech test day. The test was pretty much building something with this new tech. I'd never claimed to have any experience of this at all - so I was completely cluess.
They asked me for interview feedback and I told them they'd wasted my time. Might as well have tested me on brain surgery - I never claimed experience of that either!
2) Got train all the way to London on premise that job was near home. Stupidly I believed agent (I was fresh out of college). 5 mins into interview they ask me if I planned to relocate - end of interview.
Agent admitted later he knew all along but thought I'd fancy living in London when I got there. Made him cough up for train fare.
3) One interview was just 40 technical questions split into groups of 10. I had no experience of one of the groups (so 10 questions I just guessed).
If I remember I still had 29 out of 40. But they gave contract to someone who had 30/40.
