QA Engineer Interview Experience - United States

January 1, 2019

Negative ExperienceNo Offer

Process

The process took 4 months. First got an OA, then a phone screen, followed by two rounds of a technical phone interview. Generally no very hard questions. The company didn't give me any feedback after the last interview. I have no idea what happened, but neither offer nor rejection letter. Very bad experience.
