You're correct, I am requesting for ISC2 to endorse. I noted down the domains I've worked in. I worry that since I haven't personally seen any Mechanical engineer with cybersecurity experience, it's not typical and would be harder to get endorsed.
Thank you for reaching out to ISC2 Community Board.
Typically, the endorsement review process runs around 4-6 weeks. Please note that there will be no interim status provided. If additional information is required or when endorsement team approved the application, you will receive an email notification from the team
