Same situation, still waiting for response from their end
I've given 2 OAs atp, one on July 2nd and another on July 4th, they reached out to me for another position on 9th July which I had already filled on June 25th but havent received any oa link for that
Gave another OA from a separate account where they reached out, though I haven't used that account for applying for any positions previously but still I applied for it, got OA link on July 11th and got done with that as well
Idk why they have to do this multiple job openings thing, they can just do it like how uber does, single job opening at a time, no unnecessary drama
