Yes this literally happened. I messed up.
Three years ago (almost to the day) I applied to a company, did their technical test, interviewed, and was offered a job. Today I accidentally reapplied, and a different person responded to my application (almost immediately, literally minutes from application) with the exact same technical skills test I had last time.
Do I tell this new person about the events from three years ago? I'd definitely take the job now, the only reason I didn't then was due to a salary and benefits advantage of an alternate company. I did my diligence and called them back and informed them (politely) that I couldn't take the position as a better opportunity arose.
