I'm quite curious. I applied for a job as an IT analyst a while back: it's not especially senior, it's the sort of thing I've done in the past, and I'm pretty confident that I'm qualified for the job.
The interview process has been quite involved: on top of three face-to-face interviews there have been a number of tests I've been asked to do, including what I was told was a 'Myers-Briggs type test' - again I've done many of these before and generally know what to expect.
The 'Myers-Briggs' test was online and only had Yes/No options for each question. The first set of questions were the sort of thing I normally expect from 'Myers-Briggs' style analysis - "I find it easy to make decisions" sort of thing - but the second set seemed to be asking for my personal aesthetic tastes - "I like to listen to classical music", "at weekends I like going to parties", "I don't like modern art" - while the third set asked exclusively about my friends and family, with questions that seemed a bit intrusive "My friends can behave in a risky way", "I would describe my family as being politically active", "My friends tend to have politically conservative views".
The role isn't managerial, isn't customer-facing and doesn't have any security requirements (not for the police, for example). I can understand how an employer might want to understand how I would behave in a team, but I can't see what my friends' behaviour or political views have to do with it at all. Without discussing the answers face-to-face it's also hard to see how they build up a picture of what I'm like - for instance, DH can 'behave in a risky way' in that he likes skiing very fast down black runs, but doesn't in the sense of, say. drink-driving or drug use - which a yes/no doesn't cover.
I'm really at a loss as to why these questions are relevant or necessary, but would love to be enlightened by HR people or psychologists - is it a normal line of questioning?
