Sure. But a form letter from the HR person saying you are not a good fit is way better than your application has been rejected blah blah blah. Tech, especially Data Science is a small fucking place. Making enemies is incredibly bad. I know that I would go out of my way to strongly recommend that any of my friends who are ever rarely in the job market to not look at that company, or the tech lead.

Also, to look at it from other point of you. I once interviewed at another startup where the guy gave me cold harsh feedback as to why I was not the right fit. I still respect him for doing that. It was not the right fit for me. But, I would heartily recommend the place to anyone else who I think would be the right fit.
