When I interviewed for Facebook, the interviewer berated me for the coding pad losing focus with an alt-tab for a second ("What are you doing?"). I wasn't aware they were tracking this, of course, nor that it wouldn't be kosher, and I specifically asked about whether I could look up Java API at the start and did not get a "no" ("We don't necessarily require working code here" is pretty ambiguous). I passed the technical round, and then they ghosted me after asking what my technical level at Google was (which I didn't have to tell, as it's hidden even within Google).
