I have got an offer from a very good company and I have also accepted it. Now they are performing background checks using First Advantage.
My current and next employer are both multibillion-dollar US-based tech companies in the area of scientific computing. A little background is that I am the highest rated employee and just last month I was promoted also. I have the review documents etc. with me. Last week I designed an end-to-end system which was very positively received by the customers and they are interested in doing business with company. Now that I am leaving, no one in team can take it forward.
My current manager is very sour that I am leaving his team. In the background checks by at new company, I was told they'll contact my current employer.
I am worried if his sour attitude spoil my chances of leaving as he might say something negative about me during the process? Last month internal reviews were all very good and filled with praises. For someone who left the team last year, he told the prospective employer that she was "untrustworthy" even though she was highly-rated also.
How do I deal with this? Will I get a chance to explain myself to my next employer in case background checks are returned bad?
