Yes, people even in post-doc positio got EB1 approved. In my case, I tried it, but they challenged everything I presented.
(1) I have publications (many, including top journals): publishing is your routine job. It does not estalish your outstanding status.
(2) I have reviewed many papers for journals, conferences, NSF: same reason above.
(3) I have two academic awards from national/international academic conferences: more statistics are needed to prove those are prestigious awards.
(4) I have 7 recommendation letters: some are wriiten by co-authors (But 4 are written by others, only 3 by coauthors!)
(5) I am th editor-in-chief of an international journal: this journal is a fledhling journal. (However, they ignore the fact that I a also associate editor for 3 other established international journals)
(6) Goodgle Scholar shows I have 5 citations and some a self-citations: However, I have more than 50 other citations (not listed but Google scholars. I provided hardcopies) that are not self-ciations. In addition, my papers are mostly new, so it takes time to acquire citations.
Given the above evidence, the immigration officer believe I failed to make a case for my outstanding status.
I have wasted years on this GC thing... I have lost interest in the US.
