Molex Test Engineer interview questions

I was reached out by a HR to organise my first online interview. It lasted an hour. Then was invited for an in-person interview at Molex Singapore for around 2 hours interview.

Interview process was straight forward but the hiring manager took offense when I told him I was still actively looking and had other interviews aligned for later dates. It's a fairly common thing to let hiring managers know in my opinion.. Especially when they ask you how urgently you might need a response regarding their decision on your candidacy. But when my third party recruiter reached out after the interview he said it made me seem condescending or over confident?? Either way, it was kind of weird. That was the first (and only) time I received negative feedback for that kind of thing.
