Responded to listing back in early June. Received automated thank you. Did not hear anything until July. Recruiter called to say liked my resume, set up call with hiring manager. Manager started off the conversation by letting me know why it was so long until they reached out. They had done full first round of interviews, but no ideal candidates came out of that, so they went back to resumes again - and I am first one they called out of that batch. I really appreciated knowing this off the bat. Going in for formal interviews.

Pretty standard types of questions. The hiring managers were very specific. But no real grilling. It was professional but informal, and it was closer to an informational interview rather than a full-blown job interview.
