HR requesting meeting after panel interview - tempted to think it is a good sign -- thoughts?

Hey folks: Curious to know if anyone has experienced something like this.

My Director was let go in January. He "failed upwards" and quickly found himself a role as a RVP in a new company. He suggested I take a look at the new company and helped me to secure an interview.

First talks were simple screenings with a Junior Talent Acquisition person. That seemed straightforward. Next stop was a half-hour with the actual hiring manager. I did my homework, and the first talk went very well. Hiring Mgr told me that the process would move rapidly and that I could expect a panel interview that was a role-play case-study type of interview, followed by a one-on-one with an executive. The Jr Talent Acquisition person confirmed the process and commented that my interview was strong. The panel interview was setup immediatley.

Panel interview felt very positive as well. I was told to expect to hear back in a week. After a week, there were only cricket sounds, so I reached out via LinkedIn with some relevant follow up and some questions. The hiring manager responded quickly via LInkedIn and repeated that my interview was strong but that they had one additional interview before deciding who would move forward. The Junior Talent Acquisition person echoed this an hour later via email. The Jr T/A said that I could expect to hear something early the week of 7/7

On Wednesday 7/3 a new person, a Senior Talent Acquisition person wrote via email to introduce herself. She apologized for being out of office during my interviews and asked me for a fifteen minute call on Tuesday the 8th.

Does this step seem normal or strange from y'alls experience? Any idea what to expect?

Thanks,
