The ones I read tend to split into two categories. The anodyne: "Reading, cinema, travel". They may as well list "breathing" as an interest. I like breathing, after all. The only people who don't like breathing are zombies. Admittedly, I've employed zombies before (it's all I can conclude from the available evidence and their fitful animation around lunch time), so there may be a point here.
Then there are the ones that take it other way and try too hard to impress. I had some guy who claimed his hobby was running a dive school each summer in the Bahamas. Well, that's rather cool, thought I. So cool that I called them to check. I work in sales, so obviously we want to employ sociopathic bullshitters, but they have to be good sociopathic bullshitters.
Snorkelling while on holiday isn't 'running a dive school.'
I flipped the lever and another candidate dropped down the chute to the shark tank. Outswimming our toothy little bendy fish friends shouldn't have been a problem for someone with his ninja scuba skills after all.
It's mostly social Internet bullshit these days. Everyone has invented some kind of app-shit with their mate in their flat in Hoxton. I am not fooled, these are the same people who would spend half their first day trying to find the 'on' switch on their PC. Probably because there isn't an app for that.
Really, this is not proving a healthy diet for a shark.
