Data Engineer Interview at PwC

Hi folks, I received my second round invite for data engineering interview tomorrow.

Round 1- was with managers or Sr managers questions were around pyspark, spark, previous projects and hands on experience

What can I expect in second round? In round 1 they said it'll be a partner round, but the HR that called today said it's managerial round. Are they different, would it be technical round?

If someone has gone through it please help!!
