Why PIVOT in Sql server output one row only?

Tabl: Occupation (Name, Profession)

Name    Profession
Zahid   Engineer
Rakib   Doctor
David   Singer
Farid   Player
Arif    Doctor
Tarik   Singer

Expected Output:

Doctor Engineer Singer Player
Rakib  Zahid    David  Farid
Arif   NULL     Tarik  NULL

I tried:

Select Doctor, Engineer, Singer, Player 
from 
( Select [Name], Profession from Occupation ) T1
PIVOT
(Max([Name]) for Profession IN ( Doctor, Engineer, Singer, Player)) T2

But, It output only 1 row:

Doctor  Engineer    Singer  Player
Rakib   Zahid   Tarik   Farid

With no GTD of order

Select *
 From  (
        Select [Name]
              ,[Profession]
              ,RN = row_number() over (partition by Profession order by Profession) 
         from Occupation 
       ) src
 Pivot (Max([Name]) for Profession IN ( Doctor, Engineer, Singer, Player)) pvt

Results

RN  Doctor  Engineer    Singer  Player
1   Rakib   Zahid       David   Farid
2   Arif    NULL        Tarik   NULL

Perhaps what you need is an arbitrary ROW_NUMBER value in your derived table:

WITH Occupation AS(
    SELECT *
    FROM(VALUES('Zahid','Engineer'),
               ('Rakib','Doctor'),
               ('David','Singer'),
               ('Farid','Player'),
               ('Arif ','Doctor'),
               ('Tarik','Singer'))V([Name],Profession))
SELECT --P.RN,
       P.Doctor,
       P.Engineer,
       P.Singer,
       P.Player 
FROM (SELECT [Name],
             Profession,
             ROW_NUMBER() OVER (PARTITION BY Profession ORDER BY [Name]) AS RN
      FROM Occupation) O
PIVOT
(Max([Name]) for Profession IN ( Doctor, Engineer, Singer, Player)) P;
