Seasonal jobs that might turn permanent - what worked for you?

A staffing agency says some roles convert to permanent after 6 weeks. I do not usually post, so bear with me. I would like to avoid a gap in my résumé. Has anyone been converted to permanent?

Ask early about permanent openings. Some teams fill them from their seasonal list.

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
