面试后写这样一封信合适吗？ （最近总感觉晦气十足）

Hi XXX, XXX and XXX,

First, I would like to thank all of you for last Friday's interview. Many
of the questions were quite interesting. I really enjoyed them!

Also, something different came into my mind about the XXX question. (Not trying to make a fuss, but only hope to
clarify the answer for learning purpose.)

I guess the key points (which I missed out) are 1. xxxxxxxxxxxxxxx 2. xxxxxxxxxxxx.

Glad to figure it out.

Thanks again for the great opportunity.

Wish you have a good time in XXXXXX!
