FEI Systems Account Manager interview questions

Video interview with recruiter. I was advised next step would be with Hiring Manager/team. I was promptly contacted as my experience closely matched the position and interview was scheduled the next day. Interview was pretty basic to the HR Screen. Broad questions; "Tell me about yourself" to more specifics: "Tell me about a challenging time". Wasn't a lot of opportunity to get into detail as it was only 30 minutes and a good portion was an overview shared on the organization. It very much felt like just a screen to make sure experience/salary matched. I felt I hit all relevant marks. I was told I wasn't moving on about 10 days later. The reason being was that there were a lot of applicants and they had to move quickly. Seemed strange though as I closely matched but as an applicant, you just never know who else is interviewing.
