Answer 1

Try this:
declare #x table (Job_Name char(1), [status] varchar(15))
insert into #x values
('a','failed'),
('b','completed'),
('c','waiting'),
('d','failed')
select * from
(
select 'col' + CAST(ROW_NUMBER() over (order by job_name) as varchar(2)) [colName],
[status]
from #x
) as [toPivot]
pivot
(
max([status])
for
colName in([col1],[col2],[col3],[col4])
) as [p1]
union all
select * from
(
select 'col' + CAST(ROW_NUMBER() over (order by job_name) as varchar(2)) [colName],
Job_Name
from #x
) as [toPivot]
pivot
(
max([job_name])
for
colName in([col1],[col2],[col3],[col4])
) as [p2]

Using a Dynamic Pivot
SET NOCOUNT ON
IF OBJECT_ID ('tempdb..##Tmp') IS NOT NULL DROP TABLE ##Tmp
DECLARE #sql NVARCHAR(MAX)
DECLARE #cols nvarchar(max) = ''
DECLARE #hdrs nvarchar(max) = ''
DECLARE #Cols1 nvarchar(max) = ''
; WITH T (JOb_Name , Status) as
(
SELECT 'a' ,'failed'
UNION ALL
SELECT 'b' ,'completed'
UNION ALL
SELECT 'c' ,'waiting'
UNION ALL
SELECT 'd' , 'failed'
)
SELECT *
INTO ##Tmp
FROM t
SELECT #hdrs += ','+QUOTENAME(JOb_Name) + ' AS Col_'+ CAST(ROW_NUMBER () OVER(ORDER BY job_Name) AS nvarchar(5))
FROM ##Tmp
ORDER BY JOb_Name
SET #hdrs = STUFF(#hdrs,1,1,'')
SELECT #cols += ','+QUOTENAME(JOb_Name)
FROM ##Tmp
ORDER BY JOb_Name
SET #cols = STUFF(#Cols ,1,1,'')
SELECT #Cols1 += ','+QUOTENAME(Cols)
FROM
(
SELECT Job_Name, 'Col_' + CAST(ROW_NUMBER () OVER(ORDER BY job_Name) AS nvarchar(5)) Cols
FROM ##Tmp
) X
SET #Cols1 = STUFF (#cols1,1,1,'')
SET #sql =
'
SELECT *
FROM
(
SELECT Job_Name, ''Col_'' + CAST(ROW_NUMBER () OVER(ORDER BY job_Name) AS nvarchar(5)) Cols
FROM ##Tmp
) x
PIVOT (
MAX(Job_Name) FOR Cols IN ('+#cols1+')
) P
UNION ALL
SELECT '+#hdrs+'
FROM ##Tmp
PIVOT (
MAX(Status) FOR Job_Name IN ('+#cols+')
) P
'
exec sp_executesql #sql
DROP TABLE ##Tmp
