Note: I trashed this blog post several times. But I would like to express my point of view (hey, this is my blog. :D ) Some weeks back, I had an interesting discussion with a HR consultant. Bottom line: You ruin your career, if you stay for more than 3 years at the same company. IMHO this is bullshit. I have started my IT career, right after school, with an apprenticeship at a local IT company.
