You're correct, I'm not a sales person, which is maybe why I'm finding it hard to be sympathetic to her firing.

"She closed zero sales 4.5 months into a 3 month ramp."

She had 1 month, after 3 months of ramp, to close something. Based on that, alone... I'd still stick by my comments above. If she has even a single peer closing even a single tiny deal in that 1 month, then she's already at the bottom of the list.

1 month, 2 weeks of which was holidays. As someone with extensive sales background, I'd advise you to step back and realize your judgements are heavily under informed.

Either I'm really dumb at math or you're not doing it well.

  3 months ramp.
  1 months sales.
  2 weeks holiday.

  4.5 months

It is predictable that you'd throw out the appeal to authority fallacy.
