This is nothing how it will be during the rush hours in Pune, special in Swargate. Swargate is a huge bus station.
How to get on a bus in India is to be ready and sometimes run to the bus. To get on the bus you need to push and be push.
Sometimes the bus is just to crowded to get on and which mean, wait on a other bus. The timing does not exist, so it is just wait.
