As Peter indicated, all people who become arahants go through the stages of sotapatta, sakadagamita and anagamita. In the suttas, you will find instances of disciples who appear to become arahants almost instantaneously. Almost instantaneously, but not instantaneously.
With these notable noble ones, their journey through the stages occurs incredibly rapidly and is due to the accumulation of paramis over many hundreds of thousands of lifetimes. For inspiration, you might like to have a look at Great Disciples of the Buddha, edited by Bhikkhu Bodhi.
“No lists of things to be done. The day providential to itself. The hour. There is no later. This is later. All things of grace and beauty such that one holds them to one's heart have a common provenance in pain. Their birth in grief and ashes.”
- Cormac McCarthy, The Road
Learn this from the waters:
in mountain clefts and chasms,
loud gush the streamlets,
but great rivers flow silently.
- Sutta Nipata 3.725
