[Question] Examples of people who didn’t get into EA in the past but made it after a few years

Hi,

What are the examples of people who tried to get into EA in Research (e.g., @ GiveWell, RP, CE, ACE etc...) or as a Program officer, didn’t get in when they tried but got in after a few years?

What did they do in between to get a EA research position a few years later?

Can you state which position you didn’t get and which position you got a few years later, and what you did to improve?

Thanks.

P.S Only actual examples please.
