No, not really personal experience, due to age I am way past any internship or apprenticeship possible offer, but I have (much younger than me) cousins and sons of friends that went into the stuff (a couple still are).

Also, you are speaking about a very definite field (I presume software engineer or similar), while I was more broadly speaking, an internship at - say - a legal firm or - still say - an accounting firm or other "generic" office, where internships usually (not always) revolve around data entering, making photocopies and similar.
