Flowserve Applications Engineer interview questions

Three interviews which in my opinion went well, but three weeks later haven’t heard back, I sent a message of a follow up. On Sunday morning I received an email saying they regret to inform me that I was not chosen for the role.

3 round process. The first interview was a phone interview with a third party. The second was a phone call with the hiring manager. The third was an in-person interview with the team I’d be working with.
