Rene Said:

What should I write in a thank you for a phone interview letter to HR? see details?

We Answered:

I recommend you say thank you for the opportunity to interview, and you really enjoyed the chance to speak to them over the phone. The most subtle way I know to ask the question regarding selection is to ask something along the lines of "I am interested to know the timeline of your decision process." They may respond with we will be conducting on-site interviews on such and such dates, or they may send a letter stating thanks but no thanks. Good luck. In the future, I would send a letter like this within 24-72 hours after the interview, even with the intervening holidays.
