H1B visa application status on attending F1 visa interview.

Explanation: I had filled for h1b in year 2014. But it didn’t get picked in lottery. This year I am planning to attend visa interview for F1 visa.

Q: Would I be asked if I had applied for H1b last year and why? If yes, what is the probability that it would affect current interview?

It is very hard to say. Typically,you may not be asked about that. It should NOT affect your current F1 visa stamping at all as both are totally different. Even, if asked, you can just answer honestly, it should be fine.
