We really have openings, yes. We've made multiple hires for these open roles and continue to grow the team. We don't use any "live" project examples or farm out real work as a part of these interview tests.

Is there any evidence for these accusations? I'm impressed that they pay people to take the tests. They (seem to) do things the right way.

They only contact engineers from competitors, trying to squeeze out internal info from them, masked as a take home task.
