HI,

IJP is way to tap the internal talent & provide growth opportunities to employees.
First list down the eligibility criteria for the positon for which an IJP is been conducted.
Then shortlist candidates as per the criteria & conduct a role play or group discussion for them to identify the skills & knowledge required to be possessed by them.
Furter a final interview can be conducted with the suitable panel members to select the suitable candidate for the position

Regards,
Leena
