Which faith traditions postulate that the moment of conversion is an unmistakable event or experience?

While contemplating answers to several related questions ([link 1](https://christianity.stackexchange.com/q/99969/61679) , [link 2](https://christianity.stackexchange.com/q/99954/61679) , [link 3](https://christianity.stackexchange.com/q/99687/61679)) , I've started to have second thoughts on my original impression about the concept of conversion, perhaps wrongly understanding it as an inherently evident experience or event, rather than a more subtle, gradual, and maybe subconscious process. When I say an experience or event, I'm not necessarily referring to a dramatic Damascus road encounter, but perhaps some form of an 'aha' moment of enlightenment. For instance, Latter-day Saints have the concept of ['gaining a testimony'](https://christianity.stackexchange.com/q/99578/61679) , which appears to involve an experiential aspect, yet I'm uncertain if they distinguish it from the moment of conversion. Which faith traditions posit that the moment of conversion is an unmistakable and self-evident spiritual event or experience?
