How about switching my career from SAP to Full Stack Data Engineer ?

What does it take to switch my career from an SAP Consultant to a Full Stack Data Engineer.

I have already completed one learning for FSE which included the basics of SQL, Python, MongoDB, Apache PySpark, Apache Kafka, Power BI, Hadoop.

I have achieved a certification as well for the Full Stack Data Engineer Program.

I am just sceptical to know about the package that we will get outside if we switch our career after 8+ years in SAP. Will it be more than what we are getting or it's going to be like the one for freshers ?

How will the interview be ?
