Earlier this year, I started a new hobby. Not crossfit, brewing craft beer, or some other trendy, cool hobby. No, I started knitting socks (which, I think, is VERY trendy and cool).
Like almost any Finn, I love watching ice hockey. The World Championships every spring are of course a must, but this weekend I went to see my 11-year-old cousin play in the local league (okay, I've been there two weekends in a row now, I can't even go get a cup of coffee during the game because it's too exciting, and I got my cousin's autograph - I might be becoming their biggest fan).
Almost any job ad on any job site includes a mention about required previous experience: "The ideal candidate will have 5 years of experience in a similar role", "We are looking for someone with 3-5 years related experience", "At least 7 years of experience performing similar tasks is required", and so on.
In today's job market, changing jobs periodically is a rule rather than an exception. In fact, the rough estimate is that we change jobs 10-15 times during our professional careers. Long gone are the days when you would graduate from college, settle in a stable job, and retire decades later from the same company.
