I am not really sure what you are asking here.
Spooling output from a SQL statement has nothing to do with an external table.
You can spool a select statement whether it is an external table or a real table. the SELECT does not care.
You can spool from a table into a file that an external table can be based off of, but spool works on the client side and external table exist on the server side, so unless the client is the server, you will not be able to do that.

The interviewer may have been asking if your colleague knows that Data Pump can write to an external table. This example is from the Utilities Guide:
SQL> CREATE TABLE inventories_xt
2 ORGANIZATION EXTERNAL
3 (
4 TYPE ORACLE_DATAPUMP
5 DEFAULT DIRECTORY def_dir1
6 LOCATION ('inv_xt.dmp')
7 )
8 AS SELECT * FROM inventories;
