HCLTech Product Manager interview questions

I forwarded my resume through my known contacts. I was called for first round of interview at their Bangalore office for a short interview of 30 minutes duration by a panel of interview team. They asked me to come for another round of interview at Chennai. I was called for interview at Chennai after a week. . This interview went for 2 to 3 hours. Initial verification documents by HR/admin team took about 30 minutes. Then, I had HR interview for about 15 minutes. Then , I had technical reviews by one of the Senior Manager (Who became my boss on joining) and the Technical Head of the Facility. This technical interview was conducted for multiple rounds focussing on specific aspects of the Technology like, C, Real Time Computing, Device Drivers, Database, Application Programming and APIs. After these multiple rounds, I was informed that I'll be informed of the result over post in a couple of days. However, they hinted me that my chances of getting in are bright.
