sql order by hardcoded values

sql order by hardcoded values

I have the following query:
select 'junior' as type, value
from mytable
union
select 'intermediate' as type, value
from mytable
union
select 'senior' as type, value
from mytable
Which returns the following data:
type value
Intermediate 10
Junior 5
Senior 1
I just need to reorder it so it looks like this
Junior 5
Intermediate 10
Senior 1
I can't figure out which order by clause to use to achieve ordering by
custom specific values, how would I achieve this?
