Bank of Baroda recruits a PO in two ways. First is through the IBPS exam. Here if you clear the mains exam and perform well in the personal interviews they'll give you the job. Second they conduct their own exam. Once you clear the exam you'll be sent to do MBA in finance for a year in Manipal University. It's more like a training program where company bears all your expenses. So there's a guarantee if you've cleared the exams.
