I applied through a recruiter. I interviewed at Control Infotech (Dallas, TX) in Jan 2021
Interview
One video interview with President, CEO and Operations Manager. Very technical. Received word from recruiter that they are moving forward with job offer. They eventually passed on me because of background check. They claimed that their customers are in government sectors so candidate cannot have a criminal record. So if you have one, don't bother applying.
