According to Columbia Admissions, the committee is "in the middle of the review process of all first round applications."
At least they didn't say the committee had already finished the review of 1st round applications. I haven't gotten invited for an interview either and I'm holding out hope because of the vagueness in the statement.

For those wondering how I know this info and for those this situation will apply to:
One of my recommenders never sent her letter. I've been stressing about it for a few weeks, thinking I was sh*t out of luck but inside hoping the rest of my application was strong enough to still warrant an interview.
My old professor finally got back to me this week, saying she would submit the letter now. So I emailed admissions to see if it was too late to submit the letter. And if it was, whether my incomplete application would be reviewed by the committee or disqualified completely.
Admissions responded saying that the letter could still be submitted (almost a month after the official deadline). But that the committee was already in the process of reviewing the first round applicants. and the new letter of recommendation may or may be seen by them, depending on whether they had already reviewed my application.
Which I inferred to mean: yes, the committee (at least in painting dept) will review incomplete applications. Obviously, the application would be at a disadvantage, compared to others, but it's comforting to know it's at least considered and not totally disqualified.
