Every interview experience ever

I have been on a career break for quite sometime. It started out with dealing with exhaustion in consulting ; some girlies might know that 8 hours of work shift is 12 hours in some assignments. And eventually it turned into me taking care of my health.

I moved to a different city and thought maybe now I can start with my career again, and I started reaching out to hiring managers, HRs, updating portals, so I can get a chance. And I did! I interviewed with a company, which is in completely different industry (manufacturing), hiring manager was impressed with my experience and skills in service industry and since she had also been a part of service before, she was happy to bring me onboard. But there was one more round to go! Mostly when hiring manager is convinced, you would feel that next round, which is just a cross functional round, would be also the same.

But as I mentioned, it is a different industry, suddenly my call is scheduled with head of marketing asking me about concepts of marketing, I explained her that my experience is fairly different and concepts that I could apply to her business. She was not convinced. Her feedback added one more round of discussion with another head of department. Now I have a conversation with head of manufacturing, asking me manufacturing concepts, which I told him clearly isn’t my forte. He had clearly not read my resume, neither my domain encompasses his domain, but for sake of interview he started asking me niche questions regarding manufacturing. He asked 2 questions, when I said clearly that this isn’t my domain and I can explain examples of my domain and applicability, he concluded the call.

I am wondering, how should I even feel about this?
1st round : My domain : I cracked the interview
2nd & 3rd round: not my domain, still showed willingness to learn and asked questions. But in both rounds the interviewer wasn’t much interested once they realised the background is different, even though it’s not required in domain I work in.

Both interviews felt like I am not being heard or interviewer is not having a conversation beyond 10 mins, surprisingly my first round of interview (domain specific) was for 1 hour!

I sent a thank you message to hiring manager, stating that specific domain knowledge is may be a requirement considering the conversation, so I will wait for their feedback. I think 90% I am rejected, 10% some miracle might happen. But interviewing or trying for some months now, is making me feel not interested any more.

But I know I have to keep going.
