Agency Application Timeline w Clearance

Sorry if this is the wrong forum for this but reddit was auto deleting my questions lol. Was interested in applying for a three letter agency but am currently waiting a little longer for some mitigations to be fulfilled. The agency’s open and closing dates are well within my mitigation timeline, however I am just concerned if it is even worth applying later than usual especially in regards to the length of a clearance investigation. Basically what I’m asking is, if the close date is reached on the job posting and I am still being investigated, am I still eligible for the job slot upon a favorable adjudication, or do lose my spot? Any thoughts?
