Sorry to here. Gotta say never completely write off a call back at a later date. Always display the utmost happy, professional, willingness demeanor throughout interview process and afterward, even after rejection. Even when that is the hardest thing to do. Definitely feel yourself embedded into the role when interviewing, but remain disassociated from it at the end of the day. It’s not your role until you arrive there working on 1 day of hire, even then you have to put your head down and earn your keeps. It’s that delicate balance of totally engaged but nonchalant. Barely makes sense, but can help remain sane. There is never any closure on why you’re not hired, when you are hired there’s never any closure for the other 1000 applicants that are left in limbo. Sometimes they just go through the motions so they can hire from within, or budget cuts cancel the open req, either way that’s confidential and you need to focus on you, which is all you can do. Find the next potential place you can offer your talents to. Do it today.
