The single most disrespectful interview process I've been through.
5 or so calls, a 24 hour project for which I had to learn AWS, a technical interview, all to be ghosted.
They reached out to *me* on linkedin, after I was recommended by a friend.
These guys will waste your time for *hours* and not have the courtesy to write you so much as a "sorry no thanks".
It's a joke for a start up to behave like this. Avoid.
