use this:

declare @employee table 
  ( 
      empid int  Primary key NOT NULL , 
      managerid int, 
      empname nvarchar(100), 
      jobname nvarchar(100)
   )

insert into @employee( empid, managerid, empname, jobname )

select 1, 3, 'ravi', 'se'
union
select 2, 3, 'kumar', 'SSe'
union
select 3, 4, 'xyz', 'TeamLead'
union
select 4, 5, 'ppp', 'ProjectLead'
union
select 5, 6, 'MMM', 'Manager'
union
select 6, null, 'ccc', 'CEo'
union
select 7, 2, 'ram', 'Fresher'



SELECT 'original data', * FROM @employee;

with RecursionCTE (empID,managerid, empname, jobname) 
 as
 (
   select empid,managerid,empname, jobname 
      from @employee
      where managerid is null
   union all
   select R1.empid,
          R1.managerid,
          R1.empname,
          R1.jobname
