VEG ER for Pets interview questions

One of the senior leaders reached out to me on LinkedIn as they were hiring for their direct team. We had an introductory/exploratory conversation for the position they were filling, Senior HR Manager. From that interview, I was given feedback that it went well and they'd like to progress with me meeting with the Managing Directors via Zoom as a next step. I sent a thank you note the following day, sharing that I was looking forward to next steps. After a couple weeks without any further communication around next round of interviews, I reached out to follow up and see if they were still interested in my skillset as I was still looking to continue conversations. A full month & a half went by before the senior leader I spoke with responded to me, apologizing for the delay, and saying they'd like to continue conversations. I responded back, letting them know I am still interested and asking them to share what they are thinking for next steps. I never received any type of response back. I was blown off with no communication at all by the senior leader who had reached out to connect with me initially. I understand things change; maybe another candidate was much stronger, or the position was put on hold, etc. It is really dissapointing that after taking time out of both my day and theirs for a 30 minute zoom call and being told I'd be moving forward, they were unable to prioritize an email back to me to let me know things had changed. If I've learned anything in my career, how you treat people inside and outside your organization is a key opportunity to show off your company culture in a positive light and this experience unfortunately showed me they have some work to do.
