Attended 3 interview rounds in total, was invited to a 4th round but I did not attend. Some were face to face, some online. First interview was with HR, and was quite straightforward, mostly just introduction and going through background and interest/knowledge in the company. Second and third interview were with managers, they asked a mix of behavioural questions, as well as knowledge-based and competency questions. Also asked you to role play selling a product with them for both interviews (a pen and a product of your choice). Interview experience was also quite different among the two managers, first one was quite waffly and long-winded, second one was much more direct and straight to the point.
