"Interview
Shortlisted candidates will undergo a personal interview. This may be conducted by telephone, on a one-to-one basis or as part of an assessment center. The Company conducts suitable skills and personality tests as part of the process for selected positions. After the successful completion of the personal interview, candidates will have to undergo an administrative clearance process."
