I applied online in Jan 2019, got invitation for first phone round shortly after. I was cleared for the 2nd round with associate director, which went pretty well. Thereafter, I was invited to visit them in Ohio and meet the team. They delayed this interview by almost a month by constantly saying that people were not available. People interviewing me were really nice and polite and asked the basic questions. I had 4 rounds of interviews and all went pretty well. The HR didn't ask me the most basic questions like work authorization or salary. this seemed like a red flag. I was told I would know the outcome in 2 weeks and in exactly two weeks, I was sent the standard rejection letter.
