A dude finds you from linkedin and talks to you about your interests and tells you that they're interested. If you ask what role is it, he'd tell you, we'll hire and then decide where to put you in. You take the "hackerank" test and your fate is decided only by that algo. If you clear that, a European dude with a thick accent asks you for a probability-based pair programming assignment. Once clearing that, you'd be invited to meet their "development" team.
