The plant head will see things from a broader perspective.
You need to present yourself as a sober employee who will be beneficial to the company in terms of job out put.
He will assess your general behaviour and how well you are likely to gel in the company.
But not withstanding that you passed 3 rounds,update yourself with latest in your field

Dear Nethrao,
Thank you so much for your valuable information.
