Yes and no. Interviewing is definitely something you can become good at by practice (I can confirm). But I can tell you that studying algorithms and data structures for interviews (which I would not have done otherwise) has made me a much better engineer and I've taken a huge amount of knowledge from it that I use very often. So it's more like one of those exams that taught you a lot, even if you don't remember everything after a year :)
