Contacted a relevant prof, was asked for 1 to 1 interview initially and then a talk to his group. They were doing interesting things, and were curious about my work too. Overall, a great learning experience and motivation.

In summary hectic! I had to sponsor myself to one of the interview location and met twice virtually afterwards. This might not represent the general view, but there appear to be a bias in the employment process. People from high-ranked schools might have greater chances of being favored.

Two rounds. First meeting with the PI and presenting my research. Asked several technical questions on the presented topic. Next round was with existing postdocs and collaborators in PI's lab.
