The OP asks questions (in the sense that there are sentences with question marks at the end) but he/she seems much more interested in complaining about how they've been "abused" by the company at which they tried to get a job, almost to the extent of looking for validation versus an answer to a question.
It's a post that's attracted a lot of attention, and I think there's a potential for it to add value (as a discussion about clarity around hiring practices) but it's so mired in the rant that it feels very lost.
