You can do one level of nested query at like below

 

List<Contact> contacts = [select id from Contact c where c.AccountId in (select id from Account ) ];

 

but if you add one more level like 

List<Contact> contacts = [select id from Contact c where c.AccountId in (select id from Account where createdby in (select id from User) ];

it gives error
