I interviewed over the phone once. Then, I was asked to interview onsite, which I did. The following interview (3rd one) was via Zoom. I was told that I would hear back in one to two weeks. I have heard nothing from them. I'd be happy to get reject and just move on after so many interviews, but I got nothing. I would understand if I heard nothing back after the first application, but at least have the courtesy to email or call me after I've interviewed 3 total times. DO NOT APPLY OR WASTE YOUR TIME with OEC. Phone screened and 2 group panels.
