Gave notice. Bosses boss fired me. Had 3 job offers and a 15% raise before unemployment would have kicked in.

I told my boss I was resigning and that I'd work until the end of the pay period because they refused to assign tasks that challenge me. The day before the end of the pay period boss and boss' boss video call me and boss' boss fires me. I hung up the call as soon as he said I was terminated and was moving to the lecture phase. I had a consulting job and 2 first interviews lined up the following day and 2 job offers with a $20k raise before I was eligible to collect unemployment. I never thought I'd be part of the great resignation, but here I am and it seems to be working out well.
