Keros Therapeutics interview questions

I applied early this morning for a position that was posted for a few days. Prior to 9 am, I received a turndown letter letting me know that there were many qualified applicants and Keros had decided to move ahead with another candidate who they feel is a better match for this position. Clearly, I was not considered for this position which I was more than qualified for. Removing postings rather than sending immediate turn down letters to qualified candidates would be appreciated by many qualified applicants who take their time to consider the opportunity and apply.
