Odd but not unheard of. I got a job offer from Boeing sight unseen based on a cover letter and resume. When I asked, they did give me a site visit (though I didn't ultimately take the offer).

I know it may seem odd in a world of leetcode interviews etc. but, if you're hiring a bunch of new grad engineers for one of the aerospace boom cycles, you can save a lot of effort by just hiring a bunch of people out of schools that pass some filter.
