First round was the aptitude test with questions as per my job role. In the second round, which was the interview round, they asked me about how I think when designing, what users want, and checked if I'm good at using design tools. This was followed by a Product Head round and HR round.

It was pretty normal. The interviewer will see whether you have technical expertise and people management skill. If you've got skills, know your stuff, and can answer confidently, it won't be too tough.
