For SBI PO banking tests what is the day/month gap in between 1. qualifying tests, 2. Professional knowledge test and 3. interview?

Hi Gaurav , 

SBI PO would be conducted on four days this year which would in the end week of April and first week of May . Mains Exam would be held in first week of June . Interviews and further process would take place in first or second week of July . 

Best of Luck!!
