Apparently the only suggestion that OP's application might not have been considered was due to the fact it was filed already too late in the hiring process.

Do you think every hiring process should restart whenever a new applicant sends a resume?

...unless that stage of the process was closed already? I mean, companies are bound to time frames to fill a position. Do you think it is reasonable to delay a project just because another applicant applied to a position?

> but also, hiring the developer of an open source library that you want to use internally and paying them to both integrate the library and work further on it is an excellent way to have a sustainable open source ecosystem, which both anthropic and the developer will benefit from.

Are you sure about that? I mean, I'm yet to work at a company where a software engineer position is so reductive and constrained that a developer has a single very specialized responsibility. Taking your personal opinion at face value, do you believe a project team draws any value in hiring the maintainer of a whole tech stack if all they are looking for is someone to implement a dialog box here or there?

What's the largest company you've worked at that was a tech company?
