Corning Business Integration System Engineer interview questions

This is the worst interview process I have ever experienced in my entire life. A recruiter reached out to me for an online interview. I accepted the invite and scheduled a date. During the day of the interview, she did not show up. I emailed her several times and no response. I decided to be proactive and scheduled another interview in her calendar, maybe something went wrong. She still didn't show up for the interview and ignored my emails. This is really a messed up way to treat an interview candidate. No respect of my time and effort made into the application. Will never recommend anyone to interview with this company.
