Hard to say, lots of things I guess. One was that I was never good at the current interview triad and needed to practice it a lot. Another was my resume, not impressive to a certain kind of hiring manager and recruiter.

Still another was that I asked blasphemous questions like "will I get to sleep?" and voiced controversial views like "teams focused on quality move faster".

The thing is that you sometimes get quite daft reasons back. One place said "you gave more examples from Pivotal than Shopify". Well yes, I was at Pivotal about thrice as long, that's how time works. I just let it slide.
