How to Convert MYSQL Qury with self join to Laravel Eloquent Query

I have this MYSQL Query which has self joins:

SELECT 
    e.id as id,
    e.employee_code as staff_id, 
    e.hr_status,
    CONCAT(e.first_name, ' ', e.last_name) AS 'direct_report',
    e.user_id,
    e.company_id,
    e.email as official_email,
CASE
    WHEN e.gender_code = 0 THEN "Female"
    ELSE "Male"
END AS gender,    
    em.employee_code as manager_id,
    CONCAT(em.first_name, ' ', em.last_name) AS line_manager,
    d.id AS department_id, 
    d.dept_code, 
    d.dept_name,
    CONCAT(eh.first_name, ' ', eh.last_name) AS hod_name,
    CONCAT(eb.first_name, " ", eb.last_name) AS hrbp_name
FROM
    hr_employees e
INNER JOIN hr_employees em ON 
    em.employee_code = e.line_manager_id
INNER JOIN hr_departments d ON 
    e.department_id = d.id
INNER JOIN hr_employees eh ON 
    eh.employee_code = d.dept_head
INNER JOIN hr_employees eb ON 
    eb.employee_code = d.hr_business_partner_id
WHERE
        e.hr_status = 0 AND
        em.company_id = e.company_id  AND
    d.company_id = e.company_id AND
    e.hr_status = 0

ORDER BY
        d.dept_name,
       e.employee_code

How do I convert it to Laravel Eloquent Query?

Thanks
