After going through the comments, I decided to reject the offer from Group Operations and Technology. I verified from my personal contacts who were in the programme itself that the progression after the programme was slower for O&T compared to the other divisions. Heard that not all O&T graduates made it to Manager rank from Assistant Manager rank right after the programme, whereas all graduates from the other divisions made Manager. Graduates of other divisions typically took 3 years to hit AVP, but graduates of O&T took 5 years. Attrition for O&T is very high as well, heard that 2017 batch had about 15, today only 2 left. Half that batch left during the programme.
