I went through the entire interview process twice. The first time, I made it to the third round before suddenly being ghosted. Then, they contacted me again for another round. I went through three more rounds, including hiring manager interviews. I was ultimately rejected after the hiring manager rounds. The hiring manager round is more challenging because they really dig into the concepts mentioned on your resume.
