Fast Formula for Second Interview Scheduled event in the CSP

Summary:

Hi, We are having 2 phases for interview:-

1. First Interview
2. Second Interview

I have used the following formula to configure the CSP in both phases for the interview to be scheduled states. But as per the status of the 1st interview the state is moved for 2nd interview state also.

"CONDITION_RESULT = 'N'
CONDITION_MESSAGE = 'Debug: '

l_interview_operation = get_context(IRC_INTRVW_OPERATION, 'UNDEFINED')

CONDITION_MESSAGE = CONDITION_MESSAGE || l_interview_operation

IF(l_interview_operation = 'INTERVIEW_SCHEDULED') THEN
CONDITION_RESULT = 'Y'

return CONDITION_RESULT, CONDITION_MESSAGE"

How to restrict the FF only to check 2nd interview status?
