Adjustment of Status - I-485

I got married with US citizen a year ago on 10/2017, we applied for AOS on November 13th 2017, so we are expecting a green card interview soon. I have an EAD on my hands and i work since March 5th of 2018. We live in WA state but my job is located in Oregon, 3 hours driving, so i'm out of home 4 days per week (Monday through Thursday evening) for work. My 15 years old son stays with my husband all the time as she goes to school in WA. The reason why i'm working that far from home is i'm an engineer designer for aircraft companies, i applied for Boieng in WA, they would hire me but they requested a Green Card, this is their policy, they don't accept an EAD, they would like US persons or Green Card holders per their ITAR policy, so i found a job in small private aircraft company here in Oregon.
My question is that gonna be an issue on interview? If they ask what should i tell about my work? How should i act now, just quit the job before interview or any other solution, please help, i would really appreciate an any of your recommendation.
