I was terminated during extended probation, due to a mismatch between my seniority and my competence, according to my boss.
This was my 6th month, and although my colleagues don't agree with her and everybody acknowledges my skills, she terminated me saying I was not competent enough. I always felt she had a grudge on me since my first month.
Indeed, my last day was on June 20th, and I new employer made their offer on June 22nd.
My last job interview was on June 12th, where I was threatened to be terminated at the end of the month, but I didn't mention any of it, to my back then potential future employer.
The thing is that to my knowledge it's very uncommon to be terminated if one had to resign from a previous job, unless there was a severe mistake made by the employee.
Would my new employer be worried if they discover (through paper work) I was terminated instead of naturally resigning?
